I never used to get them, but I do now... I think it came with age for me (early 40's now). Had family over yesterday and felt miserable all day while I was smoking up ribs on the grill. Result of a week long binge that started on a business trip and carried right into the weekend...
Blamed myself not feeling well on a "migraine" because they all believe that I quit drinking a long time ago, which I had/did, but, well, you know... Still feel like crap today... Need to start hanging around here again more often...
