First of all, I commend you very much for your courage and your determination.

What I can say, is that being in a Macho environment is probably the closest I have felt to being free from Emetophobia. Some may not like to hear it, but there are things that benefit you being in an ultra-macho environment, and I think this is one of them. I've had the same thing playing sports, or just drinking with male friends (where people V* is quite common). I've always been quite a wuss and cowardly and when a man says, 'man-up' I feel obliged to drop my insecurities and just go ahead with things. Just my opinion.

If I was you I'd not look at it in terms of Emetophobia though. And look at it in terms of improving and toughening your character in general.
