During the height of my alcoholism, I was drinking a fifth of vodka daily, taking antidepressant meds, and smoking cigarettes. Absolutely killed my sex drive. Erections were short-lived if I was able to get it up at all and I was only 29 at the time. After a month of sobriety my testosterone production seemed to pick up to normal levels, but when I was a daily vodka drinker I had no interest in sex. Just wanted to get drunk to be honest. I lived with a gf at the time yet I had zero urge to initiate sex.
