I too went from Norco 10's to Hydro 5's then Tramadol. Granted the move from so called "narcotic" drugs was no doubt smoother when I switched to the Tram.....however, I am on day 11 of CT from the Tramadol. Never been so sick and it's not the kind of withdrawls you get from the opiates. I still hear ducks quacking in my ears and enjoy body jolts of electricity quite frequently. Actually, I happen to love music and can't handle listening to it yet! My body is just on fire! Very strange from a drug that is " non Narcotic" wouldn't you say? The rest of the fine wd symptoms include no sleep. You are wide awake.... day 11 for me ... I've clocked ,maybe 24 hours of actual sleep. Imodiem is my friend, and scattered thoughts follow me everywhere. One thing about going CT on this one, not ONE of those vicious pills will EVER pass my lips in this lifetime. I guarentee it! In all honesty, Also, I have found out that Tram made me just want more, more, more. Not addicting? huh who says? It also eccentuates the pain so you continue to use it thinking you are really really hurt. I look for there to be a big class lawsuit on this drug down the road. Best of luck to you. I just felt I had to warn you what you'll be adding with the Tramadol if you decide to pursue that out.
