Hey Troll
Beer was my thing as well (and I'm only 3 weeks clear). I imagine at 29 you feel you can handle that volume pretty well - as you get older it will take more of a toll on you physically and will probably have got more of a grip on you.
I wished I'd stopped at 29. That would have saved me lots of time and money lost to beer.
But, hey, you're miles way ahead of where I was at your age - I was firmly in denial anything was the matter. You realise something isn't right - well done!
Maybe your brother would also like to stop. Sounds like he's a heavy drinker as well if you're expecting to drink a lot when he visits. You never know he might love to have the opportunity to acknowledge he has a problem as well, if he does, and join you in heading in a new direction.
Good luck to you - look after yourself.
