Eidolon,
It sounds like you have access to proper medical attention and that you are taking already quite a few supplements following doctors' advice. My mum has never drunk and suffers from the same illnesses you are referring to. Many non-alcoholics do. I am having several problems with my bones and muscles too that seem less and less related to my drinking
For sure alcohol will only make it worse. You many not like this, but you may consider quitting the drinking for your health accepting you will not feel like a 17 years old healthy athlete either.
