I was prescribed Ambien prior to my surgery for lack of sleep from the pain I experienced. I ended up only taking 1/2 to one because they worked too good for me! I slept pretty well after the surgery due to the prescription painkillers, but once I started cutting back and then ran out, I started having issues of sleeping, but I don't think it was because of pain or anything, I think because I had gotten used to having help to go to sleep! I started taking Benadryl for help. Actually, that's the same ingredient that makes you sleepy in Tylenol PM (it is also the ingredient in Midol). For me, it was cheaper to buy just the Tylenol by itself and then the Benadryl by itself, and take the recommended dose of each. I also buy the store brands, so I really save money. To this day, I still need help on occasion, so I take the Benadryl. But the best way for me to have the best sleep is to be sure I exercise each day. If I do at least 20 minutes on my recumbent exercise bike each day, I can almost be guaranteed a good night's sleep!
