Look this pill rocks. Yes I have cotton mouth. In the last couple of months I've had it kinda back. I've been having a real hard time getting any sleep. I'm in the army so that's kinda a problem. I take 4 and hour before bed and it puts me right to sleep. I'm not saying you should take 4. Just that I do. The recommended amount is one pill. 1 pill. Other then that, its a real good sleep aid
