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.
The sarsaparilla root can affect how your body absorbs the necessary nutrients and metabolizes specific medications. If you are living with a disease and depend on efficient delivery of prescribed medication throughout your body to manage pain or alleviate symptoms, talk with a doctor to ensure that Yogi Detox tea’s ingredients won’t render your medication ineffective.
When used as directed and supplemented with a healthy diet devoid of red meat, sugar and greasy or deep fried foods, you can get all of the above health benefits of diet teas. Organic and natural detox teas support liver function and glutathione production. They also support gastrointestinal health and eliminate toxic overload rapidly from your body.
^{I don't own a scale for my own mental safety but I can see that my stomach is flatter after 2 weeks if drinking this tea. I had already reduced drinking my calories and increased my water intake before starting this tea and didn't make any dietary changes. The taste is good but I did add honey cuz I like sweet tea. It doesn't make u run to or live in the bathroom either.}
"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.
Iaso Tea claims to detox your body to help with losing weight more efficiently and clearing your body of harmful toxins. Their claims of purifying the blood and regulating bowel function also go into this category as well. The claim also seems a bit bold to us since the human body has it’s very own way of breaking down and removing these toxins such as our liver, kidneys, and skin. There isn’t much research done to prove that our body needs extra help with these functions, which makes it a bit useless. 
^{Mint Green Tea - This peppermint and spearmint green tea blend makes for a refreshing drink that tastes wonderfully satisfying hot or iced. Our gourmet tea has a rich, soothing flavor that helps with fitness goals, boosts antioxidant activity and helps stay productive. The crisp, lively aroma is a great way to ease into your morning or relax from a long day.}
Like I said in the beginning, this program stood out to me because it offered more than just tea. They had supplements and edit/workout plans to go along with the  tea! I really liked this because if you just sit on your butt all day, don’t change your eating habits and expect to lose a bunch of weight just by drinking tea, you aren’t going to like the results. Some people that have tried Skinny Bunny stopped before the 28 days was over because they already saw the results that they were looking for.

I boil 8oz of water and put 2 tea bags in at night. If I feel very bloated when I wake up, I boil another 8oz of water and put 2 tea bags in. If you are trying to lose weight, I HIGHLY recommend drinking this tea at night. I feel amazing when I wake up in the morning. I was able to lose 60 pounds and I owe a lot of it to this tea for taking the extra bloating and the edge off. I really enjoy drinking it at night too because it soothes me, and I feel like it helps my body burn more fat as I sleep.

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.
