I have experienced exactly the same. I bought Yogi Berry DeTox and after just the second day (one cup per day) I could not sleep a minute. It kept me up all night despite that there are no stimulants (e.g. caffeine) in this version of the tea, or at least none is indicated on the label. It seems that some of us just might be sensitive to some of the ingredients.
_{Iaso tea claims to provide a boost in mental and physical energy as a result of all the “detoxifying” and “weight loss aid” effects. This is one of the more believable claims (along with natural weight loss) since the tea itself becomes a big motivator for people to be healthier. Not only is the tea packed full of healthy, antioxidant-packed ingredients, but as you start eating healthy and exercising consistently, you become more energized naturally.} 

This product is absolutely horrible and made me feel worse than ever. I normally don't leave negative reviews but I feel like I'd be doing a disservice to people by not leaving this one. There's an insert inside the package that says if you share your opinion your next bag is free... so of course there are tons of glowing reviews to get more free product. But honestly I feel so bad on this I wouldn't request a second bag.

_{These bags are tasty, reasonably priced, and made with quality and healthy ingredients that you and your digestive tract can be thankful for. As long as you heed the warnings for each blend, consult your doctor with any issues that you think may arise with this product, are mindful of what you put into your body, and exercise properly, your body (inside and out) will never be better than with Traditional Medicinals EveryDay Detox.}

Tropical Chamomile Tea - With its blend of chamomile, lemon myrtle and rose hips, this delicate tea is perfect as a mid-day treat or a nightcap. This calming, individually packed tea is perfect for de-stressing after a hectic afternoon or winding down at the end of the day. It has a delicate taste and a beautiful aroma that will make tea time your favorite time of day. 

We like to look at Iaso Tea as similar to weight loss supplement stacking, but instead of stacking with multiple supplements, they are all blended into one tea. Since the tea is all-natural and not claiming to have some secret special weight loss ingredient, we can believe that the product isn’t supposed to only be a super fast-acting product. You must drink the tea over a sustained period while continuing your healthy eating and workout regimen.  

However, the tea has been shown to provide weight loss results over a period of time and for the long term. The tea is recommended to be taken along with eating healthy and keeping a consistent exercise plan to see significant weight loss results. As we have said multiple times on this site, there is no such thing as a magical pill or tea that will shed the pound off without us putting any effort in.

Skinny Bunny Tea is a collection of different teas, including their organic Matcha Tea, offering a simple solution to losing weight. These products claim to speed up weight loss and help to reduce hunger and cravings. While the Skinny Bunny Tea collection appears incredibly clean – gluten-free, dairy-free, and non-GMO – and likely beneficial to overall health, the company does not do an adequate job explaining why their tea-based weight loss program is different or superior to any of the dozens of other weight loss solutions available to consumers.
This could also be because Iaso Tea itself helps us make better decisions with our health and bodies. Since we need to be eating healthy and exercising regularly to get the full benefits of the tea, we will see a lot of positive advantages from that as well. Studies have shown that people who eat healthily and exercise more often tend to be happier and report better wellbeing. 
The original Iaso Instant Detox Tea already has a lot going for it when it comes to health and weight loss. It has a modest dose of caffeine per serving, is packed with antioxidants, and filled with natural ingredients to reach your personal goals. While the original product itself is already successful on its own, the company Total Life Changes decided to make the beverage product even better by adding CBD. 
2. Lemon or ginger tea: This revitalizing tea is great for the morning because the light amount of caffeine will wake you up without wreaking havoc on your stomach. Plus, the health benefits of ginger include reducing inflammation and controlling blood sugar, so you can feel good drinking this soothing tea. (Twining's Lemon & Ginger, $3; twiningsusa.com)
If you use a good acne clearing facial cleanser and toner, wash your face before bed and in the morning, drink lots of water, and yet still seem to have acne or an occasional breakout, a skin cleansing detox might be a way for you to cleanse from the inside. Some people drink these teas all month long and others during breakouts or monthly hormonal breakouts.
_{But there is a need for additional research to prove that they are able to eliminate toxins from your body. Because of this, we like to concentrate on the “getting healthy and feeling healthy” aspects of detox tea, and don’t count on them only to remove toxins. If they do, great, but what we want here are herbs that help boost metabolism, give you energy and clear up your skin. Any detox cleanse effects are just a bonus.}
Holy Thistle. Holy thistle is known to detoxify the liver, treat hormone balance, and help with arthritis. This ingredient has been used in traditional medicine for over 2000 years to treat a wide array of medical issues. The detoxifying claims are made since Holy thistle contains Silymarin, which is a flavonoid that is known to help protect the liver. 
^{Total Tea Gentle Detox tastes great and is fast-acting. Initially, you may have to go to the washroom frequently as the tea first cleanses the colon. After 2-3 days, bloating and any discomfort will disappear. You will also start to notice an improvement in your energy levels and productivity. Soon after, you will see visible changes in your appearance, get a flat tummy, and be highly motivated to eat and live healthily.}
These teas may be useful for promoting detox, but as constituted the teas are not likely to be effective for significant weight loss. Nevertheless, our research team conducted a thorough investigation on the combination of herbs present in the Yogi Detox Tea. Our findings, as well as the truth behind the effectiveness of this tea, can be found below.

Iaso tea is not a magic bullet. In fact, it’s not even that special for weight loss. So how does it help sustained weight loss? The utlity of the tea is that it serves to replace unhealthy meal options. Instead of sugary drinks or snacks, the tea steps in as a replacement to curb hunger while also delivering a large payload of nutrients to help your body detox. This lowers your daily calorie intake and thus helps with weight loss. Over time, you’ll be able to break the sugar addiction you don’t know you even have, and phase out the unhealthy foods in your diet.

I added this tea to my daily diet after taking a week off from mt diet/weight loss goals after I hit a plateau. I’m a big tea drinker so I drink it several times a day just because I like it so much and it’s better than drinking plain water. I dropped all the water weight I’d gained in my week off within two days and have been steadily losing .2-..3 pounds a day since. This is combining it with a healthy, low cal, low carb, high protein diet plus exercising 3x a week. So can I say for sure that it’s the tea that made the difference? No. But I do know I’m back on track and losing again after plateauing for a while and this the only I’m doing differently than before.
