insomnia
"I was prescribed this medicine for sleep-maintenance insomnia. When I first started taking it, I found that 15mg wasn't enough since I had bad anxiety related to the stress of not being able to sleep and I still woke up for long periods. I took 30 mg, which was effective but I felt dopey during the day and had a headache for a few hours when I woke up. After taking it for 2 weeks, I now can take 15 mg and get a pretty good sleep with no side effects."
