"i have trouble  sleeping. i am also a former drug addict. i was prescribed ambien and find that when i take it i make a lot of phone calls- the next morning i am always embarassed. last night i made tweleve phone calls including a former co-worker (20 years ago)   i left a voice message on vet&#039;s answearing service. i also discovered, to my horror, i had sent a number of emails. it is like recalling the things you did when you are drunk. the uspide i slept stright for about five hours (rare for me) and was not groggy. indeed, i enjoyed about forty-five mintues to an hour of cheerfulness i remembered the phone calls"
