Gosh, I can understand what you're saying about the painkillers.
I remember when I went for my post op, the nurse was a guy and he was quite hysterically funny. He was going through all the questions and then he asked what drugs I was taking. I went through naming all the vitamins and the Motrin and then added, oh and I do occasionally take a Vicoden ONLY before PT and ONLY if it's going to be painful stretching session. He reached over and patted my arm and said with a smirk, "it's okay, we can get you the help you need..." haha. No, I dont think one a day makes you a drug addict! I think either you like being in a stupor state or you hate it. For me personally, I hated the percocets. Great for pain, but made me cry a lot. Weird. The vicodin although much milder, doesn't mess with my head or personality, does take the edge off of the pain, but probably would not be strong enough for you.
