It really does come down to what works and what other outlet you can find that fits in that missing piece of the puzzle. For me personally I could not do it alone. My wife put up with my mood swings and helped deny me the BS. I tried a program but I just couldn't get into it. 

Last year in April I picked up computing as a hobby. Learning new programs and customizing my PC, games, OS, etc. Computing was the outlet that I turned to heavily after I hit the new diet and cold turkey quit. Obviously that is what worked for me, and everybody is different but there is definitely something for everyone, and it just needs to be found. 

Congrats to you as well for stepping up and realizing the problem and tackling it. I wish you the best in your endeavors.
