Super sadly, not a problem for me. I lost the ability to metabolize alcohol 4 years ago July. Over a 6-8 week period, it just went away. My last beer (one pint of Boddington's draught) gave me a 48 hour headache so bad, I couldn't get off the couch. Couldn't sleep. But had to walk my dogs. Eyes closed to a slit. Sunglasses on. Hand over sunglasses. Didn't help. Super painful. Only been in more pain twice (will spare you the details, but the worst one knocked me unconscious). I've had to switch to alcohol-free mouthwash and vanilla extract, it's that bad.
Quitting alcohol was the EASIEST thing I've ever had to do.
