Hey,
Take that thought of sixty days and set it aside. Just stay in the moment. Setting arbitrary goals like that (for me at least) freaked me out, stressed me out, and led me back to drinking. I'd think "Ahhh, I'll start those 60 days tomorrow" or "75 days til Christmas...so I'll just drink 15 more days then I'll do 60." God knows what would have happened if I had ever reached sixty. I probably would have drank.
I'm on day 225 or somewhere around there. 225 single days strung together. It gets much easier after the first 90. If I could give one piece of advice it would be to stay in the moment. Stay in today.
