andromeda,

Why don't you have emergency medicines in situations like this? You take all your supplements etc., but some times these medicines can help. I know that feeling of throwing up with noise which I get on certain places. Tricky thing is to find out what works. It took me few years to find out Though these meds are not perfect it can minimize the suffering and avoid a trip to ER.

Not that I am fan of meds but some times there is no choice.

Cheers!
