insomnia
"I used to take Zaleplon Sonata to help regulate sleep disturbances related to Bipolar Disorder. I took it 38 times over the course of 78 days and it was excellent in helping me fall asleep. The 39th time I took it, I experienced very frightening hallucinations and severe anxiety. The experience was made worse because I was concerned about maniac symptoms. I called my psychiatrist and he said to immediately stop taking it. "
