insomnia
"I was prescribed Ambien following an accident I had at work, I couldn't sleep due to extreme pain in lower back. I've been using 5mg for the past 5 yrs.  Craziest stuff I've ever done in my life while on Ambien was order some exercising CD's at 4am and not remembering the next morning what I had done, like I had been in the twilight zone. Trying to cancel stuff that I ordered and explain to these telemarketers that I'm on medication and don't recall what I even say prompted me to lock my credit cards at night. I'd rather get 4-5 hrs of sleep than no sleep at all. My lower back pain remains low, mild exercise no hot abs for me."
