Just curious how bad your phobia is..
I get panic attacks if somebody gets sick near me, or if I believe I may be sick..and my panic attacks feel like I'm going to get sick as well, so it makes it even worst..I often carry a Gravol with me to school, and I always have peppermint tea available at home.

I also tend to avoid foods which have made me sick in the past..I used to never eat Mexican,hotdogs and now I get a bit nervous about burgers.I often check for expiration dates.
