Moderation never worked for me. I am so much happier not drinking at all, and I have been sober about a year and a half.
This is your journey, what everyone else thinks is secondary. In my experience, only I knew how really bad it was.
I work in healthcare too, first cases and ready to go . It is a lot better without a hangover. I just feel so blessed. I did not go to AA, but I have not written it off as I need more sober friends.
This is a great forum. Read here, post here. It is very hard at first to break the habit, but it is wonderful after the first months.
Good luck
