getting it welcome.
I only just started on the thread and have only been sober since Nov 1 so it's very early days for me yet.
Like you, I have underlying medical issues, but I think that the lines between what is causing what are now very blurred. The main reason I decided to quit was actually because of my weight - I have put on so much weight I am now at least two stone overweight and it has to stop.
I even stopped taking medication that might help me because I couldn't take it and drink 
If it's any incentive, I have lost 3lbs in the six days since I quit. This isn't just due to alcohol calories, but when I am drinking I eat loads of crisps.chocolate etc. Do you do that?
I haven't really dieted, although I do plan to once I have the "not drinking" bedded in.
I suspect for me it's a crutch and a habit, rather than a chemical dependency, but it's certainly not doing me any good.
Just try it and see how you feel? Will DH be supportive do you think?
