I really should quit drinking.
You don't need to quit drinking, you just need more structure in your life. I also think you'd be a great candidate to pick-up and move somewhere new. Get a fresh start somewhere else. You'd be forced to spend more time/energy on building a new life that you'd have less time/energy to spend on boozing it up. Not that you couldn't, but you wouldn't have the cheap, easy access and free time you have now.
If I didn't have structure and a duty to my wife/kids, I'd spend a LOT more time boozing it up and partying. It's what I do when I'm bored, so I try as best I can to fill my days up in advance. And that includes scheduling days where I'm going to do nothing but drink/party/rock and act like a frat boy. I'm going to Dallas/Austin in February to see my old friends. I am going to absolutely destroy my liver and brain cells. But before I go, I'll hopefully log several miles on the treadmill, coach several basketball games for my kids, not miss a day of work and try to do all the right things so when I go, I can feel good about being a jerkass. I'll still enjoy a daily beer or glass of wine, but I can't
go to 11 every night anymore. At my age, I'll die and I just don't have the time. I can go to 2 or maybe 3 at best and I'm fine with that, though I'm not afraid to crank it up to a 7 now and then. But when I go to Texas in February? I'm going to 11. It'll be messy as hell and I'll feel like the HBO Crypt Keeper looks when the trip is over, but I plan on enjoying myself before returning back to normal life.
Anyhow, seems like you go pretty hard on a nightly basis, which can take its toll. I wish you all the best and hope you are doing okay.
