I am 29/W/M, and have drank at different speeds in my 20's and am very familiar with my tolerance.
This year I have blacked out twice: once after a wine tasting, and once after 2 and 1/2 beers at dinner. Both times I went from 100% fine to weak/faint, stayed weak for 30 minutes and then suddenly blacked out with maybe 2 seconds notice. Then I would take it easy that day. No headaches, no vomiting/pain.

Im 37 now and have been drinking moderately to heavily for over a decade until around two years back when I developed this intolerance alcohol - beer/wiskey/vodka/wine etc etc . Even if I have a drink or two I get really really sick. This sickness last around 2-3 hours and then slowly fades away. My eyes become red, my pulse races and have some very uncomfortable feeling. What on the earth happened to me????

Hi! I'm 25 and have been having the same issues. I went to an allergist and found that I have an allergy to yeast and mold. Unfortunately, they couldn't really narrow it down from there for me. I have figured out that brewer's yeast is a definite issue. If you have a yeast allergy, or if you think you might, make sure that the vitamin B tablets say "yeast free" on them. Most B vitamins have high amounts of yeast in them, I've found and can actually make what you're feeling worse. The other things I've found is to avoid cane sugar, processed sugar, and artificial sweeteners. I've noticed that I don't react to agave though, so I can still have that. And, I've also noticed that I can have tequila and mezcal based drinks as long as they don't have sugar or simple syrup in them. Also be careful that your bartender doesn't mix the tequila with other bitters or alcohols. This has been my experience anyway.
I have just started to have this problem all it takes is one drink and it doesn't matter which alcohol it's all the same I've had a headache now for 2 days and I feel terrible none of my friends have this problem so it looks like I'm off all alcohol sad to say and I never drank much anyway, this last headache was from one beer.
Have you checked for parasites? I used to drink socially no problem, then suddenly became violently ill (vomiting, etc) if I drank just a little bit (one or two glasses of wine). This went on for three years and I had every test imaginable done, all with normal results. Then someone suggested I test for parasites. Since that was the only thing I hadn't had a test for, I figured, why not? And come to find out, that's what I had. As soon as the treatment was over I went back to drinking alcohol like nothing ever happened.
