There's no /medicine/ or /doctors/ on fuckchan so I'll take this to the most relevant place, or maybe /trash/ would be better...
For the past 3 years I've drunk 30-45 standard drinks every day, for THREE years, erry day. I recently went to the doctors due to worries over my health over the extreme alcoholism as I've finally decided to try and stop drinking. My GP ran numerous tests after I told him my level of alcohol consumption, none of which I understood, but all of which needed my piss and a surprisingly large amount of blood.
Cut to a week later I get the results back. My GP says I lied to him about how much I drink as the most pressing issue he found was a lack of vitamin D. So I really need some nerd to tell me what's happening? Am I actually god? Do I have magic genes that let me consume huge amounts of alcohol and drugs (I also do huge amounts of drugs but didn't tell my GP)? Can a tolerance to alcohol build up to the level I need 30-45 drinks to feel drunk? Or have my insides deteriorated to the point most tests cant give accurate results?

TL;DR, how can I drink more than a cow and not die
