I've been taking Ambien for insomnia for 6 months. It's prescribed by my psychiatrist, who has been treating me for over 5 years for bipolar disorder. I've done some online reading and research about its use and dangers regarding addiction. It mentions regular long-term use can be addictive, but I can't find anything that says exactly what's considered long-term use. I also read about the dangers of attempting withdrawal on your own. My doctor recommended that I only take it when I'm in bed for more than 20 minutes and can't get to sleep, ie, not necessarily taking it every single night. I'm getting a little concerned about extensive use. Can anyone shed some light and personal perspective on this? Thanks!
