"when it works, it works well with no next day grogginess.  i am a long time user, beginning in 2001.  i have pretty much stopped, after using it every night for 9 years.  i have tried lunesta and i sleep two hours even with double dose.  rozerem had no effect.  i may be trying seroquel next.  i had night-time events with no memory of them. i typically had one event every few months, but some were potentially deadly.  yes, i too cooked all the time with no memory of it.  i would wake up and crack eggs in the sink and food on the table.  i also (very important), would go on line, send e mail that was highly damaging and/or embarrassing and have no memory of doing it until i got responses. also night driving with no memory of the event."
