insomnia
"I was given this medicine to help with sleep. I'm supposed to take one 50mg tab at bedtime, which I was doing. The doctor told me that it would make me groggy for a day or two. The first night I slept for two hours, woke up for two hours, then slept 14 straight hours. I assumed I slept that way since it had been a while since I had more than 3 hours of sleep a night. The next  dose I slept off and on the whole night and following day. I couldn't function with this medicine. I kept taking it for a week and a half thinking my body just needed to adjust, it never did. The night I stopped taking it I slept four hours, but I was able to stay awake and function the following day"
