Going out and drinking a quarter of what I would 10 years ago (when I'd wake up feeling fresh and raring to go) and feeling like utter crap!
I'm 46 now and go out as much as I did in my younger days, well at weekends anyhow. Didn't really go out at all about 10 years ago, sick of pissy lager, not a spirit drinker and thought real ale tasted shit too, having only tried a few. I hardly socialised at all.
Roll forward a few years, I discovered real ale actually tastes rather nice.
However, the down side is the hangovers, I feel like absolute crap the next day and takes forever to shake-off, not really tried hair-of-the-dog as I can't stomach drinking any alcohol the next day.
If I go on the sesh today I may try it tomorrow though.
