M37 – Can’t handle alcohol anymore like I used to – unable to sleep / digestive issues

I usually only drink a few beers per week, nothing special. Over the years I’ve come to realize I can ‘handle’ the alcohol worse than before.

If I drink, say, 3-4 beers or more, I’m pretty much guaranteed to get:

– Inabillity to sleep for most of the night
– Heartburn – stomach acid coming up
– Diahrrea the next day

Wine gives me similar problems, minus the diahrrea. I can handle 1-2 drinks, but more than that and I run into these problems.

5-10 years ago these weren’t issues. Also, my dad can handle it just fine (and much more than that). So what could have caused these changes?

Why can’t my body handle the alcohol like it used to? Anyone else has something similar?
