Congratulations! I do too, I avoid situations where people are getting sloshed but when I can't avoid it I find myself pitying the fool who doesn't realize we're not 21 anymore and the 30+ year old hangover is going to have them down for days instead of a few hours lol.
I was nearly 230 lbs when I stopped, pear shaped and unhappy. I'm now 185~ and much more proportioned for my lanky 6'2" frame. Mental clarity is huge, thank you for sharing.
I went on a comment rampage overnight and throughout today :) all good now. Starting to get to know some folks it's pretty cool that we're all in the same state.
I'm glad you got away from both, opiates took my cousin about a decade ago. Nicotine is a tough one I agree, no real immediate downsides it's just the delivery mechanisms that'll get you.
