I battle one of the worst kinds of cancer, and it there isn't any data that alcohol makes it worse. However, god, after one of the worst living situations of my life, I moved and was FUCKING FINALLY ABLE to remove alcoholic beverages from my diet, after many failed attempts including many stop drinking-style subreddits lol.
One thing that happened when I stopped is I went from 5' 10," 196 lbs to 164 in 6 months. The weight was just like, "see ya."
The weight loss alone will help me survive longer,
so I got that going for me,
which is nice.
