"i&#039;ve been on ambien for years; no problems.  i&#039;m 6 months out from having gastric bypass surgery.  two months ago, i started waking up in the night - restless, agitated, heart pounding, feeling like i couldn&#039;t get a deep breath of air so i could relax, racing thoughts..., horrible!  then started doing strange things in sleep (eating, no recollections of having done certain things).  quit taking ambien per doc&#039;s recommendation but now i can only sleep 2-3 hours a night.  have tried herbal supplements with no luck.  think i&#039;m going to try ambien again. maybe 5mg at bedtime, and another 5mg when i wake up accompanied with a xanax.  hope it works!"
