Oh god, for your own sake, stop taking ambien...immediately if not sooner! Before I knew I was celiac I was having terrible problems sleeping...so my dr. prescribed ambien...2 yrs later I found out about the celiac and went gluten-free, but by then, it was too late...I was hopelessly addicted to Ambien. I tried breaking it in 1/2, to start weening my self, no luck, no sleep AT ALL on 1/2 a pill! Not even after 2 weeks! So I took 3/4 of a pill, still no sleep...so i had no choice but to continue the reg. dose. 3 years later, we lost our insurance, i could not afford to take it anymore, so I had to quit. No sleep, well except very sporadic 10 to 15 minutes of sleep about every 4 to 5 hours resulting in only about 30 a night. It was unbearable...you lose your mind very quickly with no sleep let me tell you! I started taking massive doses of over the counter benadryl to try to get SOME sleep..i was up to 8 pills! I almost O.D! I went to yet another Dr. begging for help with my sleep, he told me that ambien more than likely permanently ruined my natural ability to sleep. 10 years later I still have to take benadryl every night, though I am down to 3, plus 15 mg. of melatonin. I don't fall asleep till very late and still wake up a few times a night, but this is the best it will ever be for me...read about ambien, and stop taking it as soon as possible!
