Insomnia
"Nothing at all. I am writing this after taking 15 mg dosage. Was on Ambien generic 6.25 mg and it worked great. Then my pharmacy started using a different Ambien generic that had no effect whatsoever. Instead of just changing to the name brand my doctor gave me samples of Lunesta. I am having the same results as the 2nd Ambien generic. Calling doctor in the AM and requesting something else."
