insomnia
"This is a God send. I can't shut my mind up when trying to go to bed. As long as I go to bed within 45 minutes of taking the pill, I only need to take a half of a pill, 5mg., maybe every two weeks I'll have to take the half if I stay up too long.  No groggy wake up, to be honest, I don't think I've had any side effects or strange experiences. I've been taking them for about 5 years with the same dosage and I'm a beer drinker and it doesn't seem to effect them."
