Beer is the main culprit for me too - _ had a wheat beer after graduating my exams last year, while playing pool.
I could feel it having s strange affect on my body.
I went to take a slash, when I came back someone had sprayed deoderant or aftershave or something all around the pool table.
I've actually been drinking yougurt with probitic in it cause I hear it helps with the smell but will probably stop drinking now.
