I drank consistently for roughly ten years before I decided it was time for a drastic change. I am still a work in progress, but I am proud of what I have acheived. Congrats on being able to go over a year. All you did is slip as far as I am concerned. Pick yourself up, dust off and go again. I'm on Day 19, and my best so far is 39 days. I think my mindset is prepared to crush that previous record. In the past six months I have cleared up many things in my foggy head. It feels great!!
Healthwise, I feel a lot better to. But, I know there's a ways to go in that department. I to also worry that I may have done some damage that might not be present had I not been an AH. It sounds encouraging that your blood test came out fine. I would try not to worry about things too much. Worrying is an "expensive" emotion.
Congrats again
