wow, rode your bike from the surgury... that's hardcore!!! I got semi knocked out when I had mine out and when I came back too I'm pretty sure my first point of business would've been to jump on my bike and go home... 'cept i probably would've forgot to unlock it first or just run right in to a wall or something.
Oh and if you smoke now is the perfect time to quit... 3-4 days where you can't smoke and all you're expected to do is lie around stoned on pain killers... worked for me :-) for 5 1/2 months at least
