Hiya Mtn :-)
Congrats on getting rid of that sofa ( trigger ) great idea x
Don't worry about the food aspect and " shovelling it in" .
Getting yourself of booze is the best thing you can do , the rest will take care of itself later .
I'm 6 months sober and have put on a few kilos . But it was a trade off i was prepared to take to get off the grog.
I'm addressing that now , with lots of walking and not eating so much crap.
Get yourself in the right headspace first , it will all fall into place later .
Good for you
