Congrats on 1 week! I suggest seeing your doctor just to talk over your drinking history, your process so far and to get some blood work as a baseline. Helps put your mind more at ease as well. I was super tired for the first few weeks to the point where I would get home from work and just want to go to bed. It eventually got better and I settled into a more regular pattern. Your body is healing and using energy to do so. Keep up the good work!
