From my past experiences it will be somewhat easier. Like Some Life said though, everyone is different. You will probably have some lack of energy but not as bad as before. Granted, it won't be a walk in the park but you know you can do it. You made it through once before, so you can do it again. I would try to taper if at all possible but it takes so much willpower. I have went cold turkey and have tapered and tapering def helps. I am currently tapering now. I am having my wife hold the pills for me as I know if I don't I would probably end up taking more then my plan calls for.
Not sure what kind of surgery you had, but if you can exercise, please do. Exercise helps so much with the energy. It helps speed up the whole withdrawal process. Just hang in there and you will make it through this once again. If you need anything, please let me know. Best of luck!
