insomnia
"Worst time with this medication. Nightmares, sleep walking, severe headaches, vomiting, didn't help me sleep at all, I would wake up and sleep walk into different rooms knowing I was sleep walking but so disoriented I had no idea where I was.  On night I walked to a storage building and stripped and fell breaking my arm. I was there until the next morning because I couldn't get up and didn't have a cell phone. My father had tried calling but with no answer he finally drove up and eventually found me... I hated the hangover effect.... I hope others benefit from it."
