"I have used Ambien for 6 years. It worked very well all the time before they introduced the generic brands. The generics are NOT the same as the original and do not produce the same results. They leave me hung over and each manufacturer has his own brew thus are unpredictable in how they will perform. I have offered to pay the difference to get the real Ambien but with no success. Sure wish this wasn't so expensive."
