I'll second that! Three days on that back in August also took away my craving for nicotine, haven't smoked since August 6th and that's after 50 years of cigarette smoking.
Funny thing about that morphine, I was aware there was some pain but I just didn't give a rat's a$$.
Probably a good reason why it's a guy drug. Same experience here. Even though it hurts you can go somewhere else (mentally) and let the pain take care of itself.
Before the ladies start in I admit I don't know what it's like for you [;-)
