I think if your doctor is satisfied as regards physical and you've stopped drinking as a coping mechanism you don't need to worry about the damage from drinking. However your systems as described to my layman's ear suggest maybe you investigate the possibility of therapy. It sounds to me like maybe you are dealing with some level of depression and that is making you feel sick and tired as well as perhaps being the motivator for your escalation in drinking.

I am not a professional though so I'm not qualified to diagnose or suggest treatment. Your best bet is to get some professional help so you can get to the bottom of it and start addressing the root problems.
