insomnia
"I had a terrible experience with this drug. First of all, it still took me a long time to fall asleep. When I did, I couldn't wake myself up when I had to. I also had hallucinations of flying creatures around the room, even with the lights on, that were very frightening. The next day, I felt like I had a terrible hangover, and had a headache that lasted all day. I was drowsy all day and just had to drag my self around, even into the next day. I really think the FDA needs to review this drug! Overall it was a very disturbing and unpleasant experience!"
