I'm having surgery Monday and will need something for pain temporarily. I also have chronic pain, anyway, and need to figure out something to cycle with Advil. I can't take Advil before surgery or after for 10-14 days. I filled prescriptions for 50 MG of Tramadol and Hydrocodone 5-325. I haven't taken either so far although I did try Tramodol years ago. It made me feel really spacey and bad, but I don't remember if it helped pain or not. * Which is the stronger pain reliever, Tramadol or Hydrocodone? * I had read that Tramadol makes some people feel sleepy and others more alert. It seems to help some people with sleep, and gives others insomnia. If any of you have taken it, which effect do you have? * Are these drugs constipating? Thanks!
