Seemed like a more interesting idea to collect a variety of opinions, because googling for health questions (especially for a person with an anxiety disorder) is always a bad route for me to go. Anyway, I totally didn't expect this. Maybe it'll go away after a few more weeks. I was on average killing a 750ml of vodka or equivalent per week. Sometimes in a few days. for the last few years. So yeah, this kind of withdrawal effect, apparently I had a problem. Why didn't I think I had a problem? It didn't slow down my work or school, in fact I've been getting promotions and top grade earnings.. though I SUDDENLY realized I got 'suckier' and suckeir at my previously teaching-worthy piano skills, so that's why I stopped, for piano! Now I'm scrambling to re-learn some Mozart and Beethoven classics. Tough with this lethargy.
