I didn't.. other than a little internal 'woohoo!'. My husband wanted to go out to dinner and things like that but to me, it's not something I need a parade in my honor for. I did what I had to do to get my **** together and live my life..I do not need to be congratulated for it, I live it every day. My second year went by with even less fanfare inside.. other than some reflection about how wonderful my life is now, and then I went about my day. To me it's not like I'm doing something extra special and fantastic, I'm just living healthy.
That's just me tho
