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.

Not just any tea will do the trick, but if you drink the right herbal teas in the right quantities, you will enjoy some serious health benefits. Choose teas that contain thermogenic properties and cleansing antioxidants. When antioxidants pass through the digestive tract and fleshy tissues of your body, they exhibit a cleansing effect, support the efficiency and health of cells and their functions, and some trace amounts of stimulants have been used for ages to curb hunger. You’ll see an increase in overall health and support your fat loss journey.

Let me just start by saying this was the best choice I have made when trying to buy a product that lives up to the hype. The taste is super tasty no sugar needed. This really detoxed my system entirely, mind you normally I drink a lot of water during the day which is required in order to get better results. I also eat clean, which helps with trying to lose the pounds after I have given birth. I was stuck at a weight of 152 and even after I work out 4-5 times a week, I was getting no where. After drinking this tea for about a week I noticed this changed my hormone levels and removed the toxins in my system, thus helped getting me out of the plateau I was in and lost 3.5 pounds. I was stoked!! I knew it was because of this tea! I have my cup of tea in the morning after my workouts and drink water. Then I reuse the same tea bag and drink it before I go to bed. I rarely give reviews if ever. But thought this was worth one. Hope this helps anyone who is thinking of buying it.
Honestly, this seemed to help out with my acne. It’s been clearing up over the past few months thanks to all of the Treeactiv products I found here on amazon, but after drinking this tea every day for a week, I noticed a drastic difference. I don’t think this tea by itself will cure acne, but I definitely think it contributed to my skin suddenly clearing up like it did. I do believe this product provided the final push I’ve been searching for. I drink 3-4 8oz every day. No skipping days. 3-4 cups. Everyday. No sweetener. No milk. Just straight tea. The taste isn’t bad at all, and you get used to it after a few days. It’s absolutely worth a try if you’re looking for something a little extra to help out on your skincare mission.
Every detox/weight loss tea should include ingredients that help to suppress your appetite. These ingredients are important for weight loss because they will help keep you satisfied after drinking the tea, and not craving or reaching for other foods. By consuming them, you can keep your overall daily caloric intake lower and be more in control of the foods you consume.
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.
When keep consuming unhealthy food our body collect toxins that can't go our easily.

_{Detox teas are essentially herbal teas used to detoxify the body. They have become an increasingly popular way for health-conscious people to detox after heavy foods, alcohol, drugs, and even their livers in general. In some ways, this practice of detoxification is nothing new, and neither is Traditional Medicinals Organic EveryDay Detox Tea, which is what makes it so effective. It draws on time-tested and proven methods to purify the body and even assist in weight loss.}
There may be a lot of impressive results, reviews, and promising claims that Iaso tea really works and there may even some before and after pictures to really prove it to their customers. However, you can never know for sure if these reviews are entirely legitimate, and if the product really works for weight loss. As we have already gone over above, the Iaso Tea’s hefty claim of losing five pounds in five days guaranteed is just to good to be true. Most likely, any instant weight loss that is seen with the tea is the result of water weight loss and no actual body mass being lost. 
The Carica papaya extract plant originated within southern Mexico and Central America and is believed to have anti-inflammatory and antioxidant properties. These properties provide benefits for your weight loss and health journey by reducing bloating symptoms and protecting against free radicals. The plant also has been known to provide wound healing properties as well. 

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.

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.
