Zolpidem
insomnia
"I took my Ambien, thought I went to sleep but instead talked on the phone to my  boyfriend who told me I was acting crazy and making no sense.  I told him I was going to cook and eat all the food in the fridge. which I actually did do with no knowledge of it, there weren't even any leftovers, however all the dishes were washed and put away, this behavior caused me to gain weight as well as have amnesia for the entire event."
