Thank you for your comments. I guess I am inclined to feel as though I don't suffer from liver or gastrointestinal symptoms like some others, and that perhaps this aspect of the disease I'm thankfully not afflicted with.
While I get drunk a little quickly, I can tolerate a large volume of alcohol on occasion. As for the significance of this as it relates to the other issues I face, I don't know. I know that Dr Rosamud Vallings has mentioned that some evidence suggests that Alcahol intolerance is almost a hallmark of ME/CFS, and that one should look at alternative diagnosis in the absence of Alcahol intolerance.
I'm not sure if low tolerance counts, or where that evidence is coming from exactly, but I will be visiting her soon as I just visited my doctor today for a referral, so I will ask her and report back.
