I'm quitting drinking as of today. I'll get into AA if it proves to be a problem,
Just go to AA already. Even if you don't think you need it (you probably do!) it will show your wife that you are serious about owning your half of the problems.
I had 2 years of treatment with methimazole, followed by RAI. I became rapidly hypothyroid after (not everyone does that fast) and wasn't truly well until I found an alternative physician who treated me with Armour thyroid (the old-fashioned thyroid med made from dessicated pig thyroid). Endocrinologists don't use it much because, frankly, it's unpatentable and there are no pharmaceutical reps taking them out to dinner to promote its use. But it works way better than Synthroid esp. for someone who has had ablation or thyroidectomy.
