Physical tells in live games

[Ricardido]

Hi, just thought id share with you my demon when playing poker in a big setting- like casino etc.

Im very good at not giving away my cards through facial gestures etc, but the vein in my neck goes crazy when im bluffing/or on a big hand. Im not sure why this is (although i know its because of adrenalin rush) because im not intimidated by the people i play with.

Does anyone else have/had this problem before and what could i possibly do to prevent this. I do wear polo shirts so i can put the collar up- but id rather be able to sort it out. Please dont flame me for this post- it really is an annoying aspect of my live play.

Ric.
