insomnia
"First off, I highly recommend taking only half a pill your first time trying this, unless you are used to sedation from other pills. A whole pill is 25mg, but that left me groggy the next day to the point that I was worthless. After a few days of 12.5mg I then "graduated" to 25mg. Hell, I've even tried 50mg before because I built a tolerance to this stuff. This pill used to put me & keep me asleep, but now it doesn't keep me asleep past a few hours, so I only take 1 pill to put me asleep, then take a prescription drug that has a longer half life to keep me asleep. But overall, I like this stuff better than diphenhydramine (benadryl)."
