For me I started feeling better physically in about 2 weeks, I was still far from "right" but I felt better every day after for a good 3 months, my liver enzymes returned to normal levels after 3 months as well as the puffyness in my face, the swelling of my liver was gone at about 6 months, my energy levels still are not all the way back to normal after 16 months, but they are getting close to being back to normal, of course after drinking for 40 years I am not sure what my normal energy level really should be at 54! LOL
Mentally I still am seeing improvements. I take vitamins, I eat well, I quit smoking in Sept., I am now going to the gym on a regular basis.
No matter how long or how much one has drank, the longer they stay sober the better they will feel.
