if all you have is a little bit of discomfort the next few days and you're sober, count yourself lucky...and i so hope on the way to a brighter outlook.
i did not/do not follow AA, some of it makes sense to me, some of it does not work for me. but i do reach out each and every day for sober contact and support both here and FTF with my friends/family.
i will never forget one of the first signs of longterm sobriety (besides reduced puffy face)..a co worker told me that i actually smiled and spoke to people...i previously would just slam into my office and quietly fight off the daily hangovers. if i got to work.
even a short walk can help reduce your anxiety too. you really can do this.
