Here is what works for me:
chewing strong gum
eating anything minty
eating a fresh lemon/drinking lemon juice
talking with my mom
eating anything sour
a wierd one....thinking of oceans and the open wilderness...just earths beauty in general, and things i am looking forward to.

p.s i find it odd how some of us cant stand the thought of being sick inside...i cant stand the thought of doing it outside...i need to be at home if anything or somewhere homey but preferrably my home.
