I used to be a BIG drinker (in both being a large lardarse and that I used to consume alcohol in large quantites, and frequently) but I think I've had a combination of being bored of drinking (and the epic quests to get home, carrying people who don't know when to stop, annoying others because I didn't know when to stop etc. etc,) and the list of "drinks I'll never touch again due to stupid experiences with them" is longer than my arm, has now turned me almost t-total.
Now I rarely drink much, maybe once every quarter, and when I do it'll only be lager. The majority of spirits will make me puke, instantly, and often enough just the smell is enough to do it (infact I feel quesy just thinking about them.) Too many hours spent with my head down the pan to appreciate them anymore.
I also suffer from amazingly painful hangovers these days. I mean really bad. I used to be fine even after the hardest of nights, but now I get awful hangovers after only a few jars. Maybe my liver left home and forgot to leave a note.
