Yep. There's a lot of us man. I used/sold/cooked meth continuously (unless I was locked up) for 17 years... Literally almost died, and if I fuck up one more time (never gonna happen
) they'd start me at 25 years... I HAD to quit, and my wife and hard training and healthy diet, are the only thing that brought me back to happiness. Like you said, it's my only hobby too, damn good thing it's a gift that keeps on giving. I get the guilt too (healthy guilt) even when my wife and I are on a cruise ship, we hit the gym hard, and earn that nice feeling.
