Not the tea, but the capsules for sleep. OMG, I wish I never took it. Sleep? No. Horrible benzo W/D hell? Yup.
I don't know if the tea is as strong, so can't say it would have the same effect. I can say the effects didn't carry over into the following day, so it's effects are less than 24 hours.
Try at your own risk, if it ramps up W/D, you know to avoid. And the revved up feeling will only last a day or less.
