Another possible cause- pub glassware that has been put away/stacked while still warm/damp can make people feel incredibly drunk after just a couple of drinks due to a toxin produced by Cryptobacillus sp. bacteria. These are naturally present in water and the environment in general, and usually cause no problem, but multiply rapidly in damp, upturned glasses. [..]
Hmm...I looked that up because my workplace almost always puts glasses away straight out of the washer, warm and damp.
I found nothing at all on cryptobacillus, but it did lead me to cryptosporidium, a parasite that isn't a bacterium. Infection with that is stated to be either asymptomatic or the cause of diaorrhea for up to a month (or fatal in people without adequate immune systems).
So...are you sure?
but it did happen to me before, though it was a mate that done it and thought it would be a laugh.
