Okay first of all take your medication. You'll only get worse unless you take it.

I wouldn't worry about v*ing. I've had strep throat 4 times and never v*ed with it.

As for eating. I think if you genuinely feel like eating something....go for it. Emets avoid food enough as it is, so if you want to eat chips and guacamole. Enjoy. Besides, if you were going to be sick the very thought of them should be unbearable for you.
