Well on the other end of the spectrum, you could be like me and waterboarding yourself for a mile 2 times a week.
I did something stupid and signed up for a traithlon and have been at it 1-2 hours, 6 nights a week, and still trying to crack the swim stroke mysteries.
Still the casual smoker, but have a lot of family stuff going on along with a lot of work.
Just too busy.

I do hope for your recovery though, because I would rather have my current problem than having an essential freedom and necessity like work revoked.
I'm sure most have been there one time or another, but I wish you the best.

I'll also make mention of this site next time I light up at the bar.
