Natural tolerance to alcohol and anesthesia?

I don’t drink often at all. Months to years apart from drinking. Both sides of my family-grandfathers battled alcoholism and I am not that interested in alcohol. Lifetime DD is fine with me I want everyone to get home safely. The 2 times I have drank more than 1-2 drinks, I reached about 7 drinks the worst I feel is my forehead and bridge of nose feeling numb and that’s it. The few surgeries I’ve had the anesthesia didn’t take or they had to up the dosage a few times, and the moment it was removed I instantly woke up. Is there a correlation in any of this?
