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.
Detox teas can aid weight loss by improving the metabolic rate and decreasing water weight (by increasing the urinary output). Regular consumption of detox teas might offer positive results in terms of weight loss. However, it does not result in fat loss. You will need to make lifestyle changes, follow good food habits, and exercise, along with drinking detox teas, to lose fat. 

"Specific detox teas offer added benefits in the additional ingredients," says Villacorta. Herbs like lemongrass, ginger, dandelion, and milk thistle all contain properties said to support a healthy liver, one of those organs in charge of your natural detoxifying process. Ginger has also been proven to alleviate oxidative stress within the liver, which indirectly helps the organ perform its cleaning task more efficiently, he says.

After all of the holiday happy hours and celebrations, your body might need to hit the reset button. A natural detox tea will help get you back on track. Despite all the social media hype surrounding certain mysterious, non-FDA-approved "slimming teas," many of these products are actually laxatives in disguise that do not promote a healthy diet or weight-loss program.
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. 
I tried the Lipton detox dandelion nettle grapefruit herbal supplement green tea recently after having a cold for an easy morning pick me up. It was an interesting flavor that I somewhat enjoyed. The grapefruit flavor is the strongest in the tea and I usually don't like fruit flavored tea, but this wasn't bad. I like that it didn't make me feel jittery or upset my stomach (like coffee sometimes does, especially if I haven't eaten much yet). For me, this would be a better tea to drink before yoga. Tastes nice with honey. I like to rub the leftover herbs in the bags over my face for an easy "spa treatment" once they've cooled a little before tossing out or using in my gardening compost. Worth trying.
I bought this tea because of the great reviews & I was like looking for something to help with a bloating feeling I’d been having for weeks! I followed the directions & made sure to drink a glass of water before the tea every morning. I feel great! The bloating feeling is gone and I have actually been able to cut my coffee with a lot of cream out of my morning routine! I’ll be buying more for sure!

Mainly Iaso Tea has positive reviews coming from videos, blog posts, and online articles that are advocating the tea. Many individuals leaving reviews on the tea state that the tea worked very well for them and that they were able to lose a significant amount of weight while consuming it. If the customers are stating that they initially lost weight with the tea, then they are most likely providing information on the water weight they have lost.
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.
Samantha, yes absolutely! We don’t ever recommend “starve yourself” detoxes. There is a much healthier way to achieve great results than depriving your body of nutrients for a few days. I would recommend sticking to lighter foods though. You can detox from specific things such as sugar and carbs or you can try a smoothie/juice detox. Just try to fill up on salads and veggies rather than heavier stuff like meats during a detox. I hope that helps!
