Zolpidem
"I have been taking Ambien or its generic since it first came out in samples at my doctors office.  I quickly graduated from 5 mg to 10mg and have been on it ever since.  The brief period of time that my insurance didn't cover it, there was no relief for me. They tried tranxene (pharmacist said insurance co recommended) and that was a joke.  I too am a chronic insomniac with chronic migraines and no sleep equals migraine.  2 years ago my family Dr cut me back to 5mg  ( due to the " women shouldn't take 10mg) insomnia and migraines raged to new limits.  returned to 10mg.  Even during my brief hospital stays over the past few years, the nurses do NOT need to put a bed alarm etc on me because I suffer from ZERO side effects. This is a lifesaver"
