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.

But when it comes to detoxification, tea alone isn't enough for the job. "No one food, herb, or remedy has the ability to cure ailments or disease, nor does it have the ability to ‘detox' the body," says Manuel Villacorta, R.D, author of Whole Body Reboot: The Peruvian Superfoods Diet to Detoxify, Energize, and Supercharge Fat Loss. (This is also why you might want to hold off before trying to detox by drinking activated charcoal.)

I was hoping for a gentle detox to help me feel lighter and less bloated, but this didn't work out for me as it seems to have for others. Could be that I wasn't as bloated as I thought? I only needed to lose a few pounds, maybe this is better for someone who really needs the help? There was a coupon in the bag for a free bag in exchange for a review, which always makes me a bit skeptical of a lot of glowing reviews, maybe this was one of those situations.
Another way you can consume the tea is to drink it regularly 20-30 minutes before two of your meals per day to begin the stretching of your stomachs receptors. This sends a signal to your brain that food is present in your stomach, and the soluble fiber then enters your digestive tract 20 minutes after consuming. This can then allow your body to release hormone signals to the hypothalamus, which will help your body create the “full factor” response to your brain when eating your meal. This results in you feeling fuller while eating less during your meal and prevents overeating or snacking afterward.
This could also be because Iaso Tea itself helps us make better decisions with our health and bodies. Since we need to be eating healthy and exercising regularly to get the full benefits of the tea, we will see a lot of positive advantages from that as well. Studies have shown that people who eat healthily and exercise more often tend to be happier and report better wellbeing. 
_{EveryDay Detox Tea has an effect on the body like no other. It has shown to be incredibly helpful in promoting healthy and efficient digestion. But detox tea is not only for those who have trouble in the bathroom. In fact, some of the first herbal medicine that contained similar ingredients to Traditional Medicinals Detox Tea was first documented as being used nearly 5,000 years ago. Its purpose is to support a total feeling of health. With this kind of history, the effects of detox tea are tried and true. It could be the answer to your not-so-great feelings of bloating or detoxing from alcohol and drugs.}

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.

2. Lemon or ginger tea: This revitalizing tea is great for the morning because the light amount of caffeine will wake you up without wreaking havoc on your stomach. Plus, the health benefits of ginger include reducing inflammation and controlling blood sugar, so you can feel good drinking this soothing tea. (Twining's Lemon & Ginger, $3; twiningsusa.com)
Many teas have shown results, so what it comes down to is decide which you enjoy, which ones you can afford and consistently see results from. Our current favorite is Yogi detox teas, when we tested the teas, our tester lost 3 pounds in 2 days, just two cups of tea a day along with a healthy diet. Plus Yogi detox teas have lots of flavors to choose from, can be found in many grocery and health food stores and have a reputable, 30+ year history with consumers.
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.
