As a lot of the guys have mentioned above, things can get a whole lot better after just 1 month, physical effects all but gone and mentally getting sharper, one of the main things for me was getting hobbies back on track after drinking got in the way and kinda took over my life to an extent, my golf is now back on track to where I was a few years back and I can now drive in the morning without doubting if I am fit to drive in the first place.
