I too am tired as soon as I get home from work. I think most of it is the mental aspect. Worrying about my DUI court case, one year suspension of my license, how I'm going to get to work/keep my job that I love since I live 30 miles away, what friends and family think of me (this is not my first problem with drinking), whether I can remain sober...etc. At work I'm actually somewhat content...until this court date that is. And I'm only starting Day 5 of sobriety, lol.
