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.
Does Yogi Detox tea clean your system? Absolutely. Throughout the day, you expose your body to unwanted toxins through the air you breathe and the food you consume.

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.

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.
Of all the liver cleansing teas I have tried, this is by far the best taste. I was drinking a glass in the morning and another at night. Then I had the great idea of letting steep all day long and drink it on the way home from work; that was a bad idea as it gave me diarrhea ... so don't steep it all day. I will follow up later with the results of next blood work to see if liver enzyme levels are decreasing.
With there being many weight loss teas on the market all claiming similar results, it is hard to stay on top and reputable. Drinking tea, in general, is a great way to increase the number of fluids you drink a day while also encouraging a healthier lifestyle. However, there are many negative benefits and negative connotations against “diet teas” since they contain diuretics or laxatives, much like our dandelion tea weight loss and ballerina tea weight loss.
Throughout the making of Iaso Tea, there is a lot of care put in to ensure that the tea remains pure and potent in each of its ingredients nutrients. All of these ingredients are not only natural, but their listed benefits are legitimate and researched by science. This product being all-natural is also very safe and can be used by all people young, old, or with certain medical problems.  
As a final word of caution: Select only the best brands of organic and natural detox teas. Many teas contain chemicals, heavy metals and pesticides which will negate your detox efforts. I would also like to take the opportunity to suggest that you keep changing and/or rotating your brands of detox teas as this will make your cleanse even more powerful.

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.

In fact, there is no hard evidence backing the claims made by tea companies that their detox teas actually purify human cells.
