I've noticed that often, I can't tolerate even modest amounts of beer or wine. At those time even a couple ounces result in a mild headache, followed by being knocked down, so that I have to lay down for about 2 hours. At other times though, I can slowly have about 8 oz of beer or 2/3 glass of wine without issue. Before I got sick my alcohol tolerance was normal -- didn't drink much, but no problem when I did. But I'm wondering if I should avoid all beer, because a) obviously I no longer metabolize ethanol normally and b) heard somewhere that there may be some issue specifically with beer and ME/CF beyond just metabolizing it slowly There's some delightful blackberry wheat bear I haven't finished yet, and I'm stuck inside due to brain fog anyway. Hat to waste that, but if there are subtle longer term (more than a few hours) consequences, away it goes.
