I struggle with all sorts of chronic nausea and food allergy stuff, so I am used to feeling sick regularly. But this time it's much worse.

I believe I have FP or a SV*. I have almost v* once, and I keep burping. I'd love to hear stories of successful avoidance when one has had a SV*. Also, I have felt n* for 5 hours now, would I have v* by now?
