I can relate but in a different way. Something that ticks me off a bit is that I feel like there are people that drink, as you say, 30+ years but they don't have the health issues or aches I do when I drink. I wonder what is wrong with my body and why it can't take just a couple beers. I can't explain why my body sucks but the fact is: my body hates the booze.
A couple weeks ago blood was found in my urine which could be the start of kidney disease. If I drink my heart rate elevates really high, I sweat, blood pressure rises, my acid reflux keeps me up at night. I get bloated and joints hurt. Sometimes I would spit a bit of blood in the morning after drinking a few. My body hates the booze and it lets me know it does. I am 32 and I have some issues some 50 year olds don't have.
I think we have to accept that while some people may (or may not) have better luck with drinking than we do, you and I aren't meant to drink anymore.
