Nearly 9 months sober, I have more good days than bad days. At 3 months sober I really noticed my mental sharpness return, although I think this first year there can be ups and downs with all parts of our mind and body. There certainly is for me. A morning here and there I still wake up with a wicked phantom hangover and can barely think. I actually don't mind it as it is a great reminder as to what awaits me each day if I ever drink again. At 6 months I felt big positive changes mentally and physically LetsDance.
Patience in all things. Get 6 months then PM me and we'll compare notes!!! In the meantime, post here every day and let us know how it's going.
