Brilliant. I havecsevere sleep.problems and used alcohol.as a means to sleep. Doctors I went to suggested alcoholics anonymous, Very frustrating because alcohol is not the problem , getting to sleep is. Bought this stuff, first time nothing but second night brilliant. Slightly dizzy but definitely ready for bed. Went to.sleep about 9.00pm and woke at 4.30 am feeling refreshed. Got me, totally convinced after years of alcohol use and abuse. Try and stick with it, first time very little effect. Second time awesome, third time one cup and off to bed..wish I knew about it years ago..
