insomnia
"Ambien itself is fantastic, never missed a night of sleep and 8 hours a night. On the other hand, this generic zolpidem tartrate is absolute garbage. I've tried for a very, very long time to see if it would work and it never has. I noticed it slowly stopped working when I picked up the new prescription for what I was told would be ambien but was the zolpidem. I do not only barely sleep with it, I do not sleep at all when I take it. Keeps me up until the next night, makes me feel mildly high without sleeping, and they just do not work at all. I've read so many reviews in the past hour or so sharing the same experience. Cheaper is not better when its prescription meds. Someone should tell the moronic Big Pharma companies."
