Well, I was an alcoholic for 2 years, and I sometimes drank up to 2 bottles of vodka a day. I landed in the hospital twice, couldn't remember how I got there either time.
From my alcoholism, I ruined my heart (though one time I took 20 caffeine pills when I was stupid drunk, so that time damaged me the most I think). Now even the slightest effort has my heart beating at like 200 bpm. My pancreas is fucked too. I suspect I have some early form of diabetes on top of my pancreatitis.
Other than that, I never exercise and I eat very poorly (mostly sweets). I'm fat too so that doesn't help. I have acne, lately even on my actual head, in what remains of my hair, very annoying.
My eyesight is also fucked so there's that.
And my back hurts even just from sitting in a chair all day so that can't be good.
Ohh and I have in-grown toenails, even though I had surgery for that a few times.
And I broke 2 font of my teeth when I was an alcoholic, they were fixed but there's still signs they were broken. Ohh and I have like 6 teeth with shitty crowns put in them, so I go to the dentist often.
