Spy it's never to late. I drank for over 30 years and I just hit my 6 month sobriety milestone yesterday. After 3 months, I started seeing improvements in skin, muscle tone, hair, vision acuity and many other positives.
Recovery is not a straight line endeavor. You'll have many ups and downs along the way and at times it might seem as though you take one step forward and two steps back, but that's okay. As long as your not using, know that your body and mind are healing.
Eat well, exercise, drink lots of spring water, meditate and hang around SR. It's definitely not to late for you.
Congrats on 3 days!
