I am now a week sober after 4 years of drinking. My mind was in it to stop drinking but day 3 I had anxiety, the shakes, insomnia, night sweats, and a feeling like i needed to do something. Funny, but I have still been a avid runner for 17 years. I stopped for 5 months and started up again this week. I can honestly say that the exercise helps immensely with withdrawals. After a good run I am relaxed, and the shakes stop. I am more focused too so I can stay on track. If you can....exercise the pent up energy. It will help. I wish you much on your journey.
