insomnia
"I find that if I take the Ambien and go directly to bed it works very well.  If I take it and then delay going to bed by doing dishes or cleaning before bed I have unusual effects.  After sleeping for a very short period of time I will get up, go to the kitchen and make waffles.  This has happened a handful of times.  I'm always surprised to have my family thanking me for taking the trouble for making waffles.  Really no trouble since I don't remember any of it."
