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.
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!
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. 
While the benefits are plentiful, there are some important side-effects that you should keep in mind when drinking these teas. For example, when drinking the Original EveryDay Detox Tea, you should consult your doctor before if you have a history of gallstones or other digestive issues. The EveryDay Detox Tea Lemon can cause allergic reactions in those who are allergic to stinging nettle, dandelion, or burdock root.
