Just had a thought. Maybe it's a placebo-type reaction (would this be the correct expression?). If one didn't know it was Guinness, or put it in a Murphy's glass, would the same reaction occur?[/quote:1hm41k32]
I had considered this , but seeing as how I had nothing against Guinness to begin with , and the fact that the symptoms are specific ( as in I've vomited from drink before and it doesn't hurt like this does )
Also I suspect that on the rare occasion in the middle of a session the possibility of me drinking an accidental Guinness has resulted in side affects prior to me knowing that I may have drank one .
Like all allergic reactions , It wasn't as bad the first few times . I drank about 5 pints the first 2 - 3 times , But each was progressively worse .
