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&#039;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."
