I find that I cannot get to sleep even on 20 MGs and if I do, it only sleep for three - four hours and cannot get back to sleep. I have also had strange things happen, I was in a motel and got up to use the restroom at night. When I got in there, I noticed a small red light on my cell phone charger. For some reason it mesmerized me and I sat and stared at it for the longest time. It would get bigger and then smaller and seemed to follow me around the room. I started taking Ambien and have no problems now
