Re read old posts, like Dee suggests. I do that now and then and my posts from my 2016 class are an amazing virtual diary. They're desperate, sad, emotional, elated, happy, confused, scared, funny, grateful, thankful, boring at times, mundane, cheerful, optimistic, boastful, .... well, pretty much everything you can imagine. It's great reading and every time I do I always come away firmly resolved that I am Never. Going. To. Drink. Again. And for 17 months it's worked.
