So EBV was my trigger as well. It was not fun. I couldn’t get out of bed. I felt so horrible. 3 weeks into it my liver enzymes were elevated, i had pain to my liver requiring prescription and the ultrasound showed ‘sludge’ in the gallbladder. Would I think to drink alcohol at that particular time? Hell, no.Same. Straight after I got EBV, I noticed alcohol made me feel sick
2 months into it, i tried to return to work, it did not go well. I still had sludge in my gallbladder.
The gist of it is, viral infections are known to be hard on the liver

And liver inflammation and alcohol don’t mix well.
The other concept that is well established is alcohol tolerance. If you are a drinker, chances are you can tolerate more than a non-drinker. How much you weigh will also affect tolerance, so a 6’5’ 250 lb guy will be able to easily tolerate 2 beers while a 5’2” 105 lbs woman would not.
Lastly, what we all mean by intolerance matters. We may all have different explanations and individual responses depending on dose, whether you have an empty stomach, whether you are ingesting fast or slow, and whether there are drug interactions, just to name a few.
