P.S. nobody can make up your mind for you and should'nt try.that should be your decision alone but you should not have to completely give up something you love just slow the pace down and enjoy the ride.
I don't race but I would agree w/above statement & pretty much everyone else's.
The main reason I replied to this is to warn you about pain killer's, I got some friend's who eat 'em like Tic-Tac's, I've seen how they look & feel when they run out of their prescription. Me myself, couldn't let anything get ahold of me like that, not saying that you would 'cause you said you don't like taking them which is good. Just be careful w/ them & maybe just take a break for awhile.
Good Luck w/ whatever you decide to do.
