i loathed throwing up all my life, even tho its normal and helps get rid of bad crap, i hated it
it got worse after i got pregnant and ended up with hyperemesis with two of them
uncontrollable vomiting, in and out of the hospital, even when nothing is in your stomach, you throw up stomach acid, etc etc
cant keep down a sip of water even and i lost 35 pounds with my first pregnancy
ended up with a lot of symtoms of bulimics, lesions in the esophogus, etc and still recovering years later from spasms in my stomach that caused so much pain once i passed out and ended up in the ER
so, now i hate it ever more after all that and yes, if someone vomits i run and avoid it... but not for 3 weeks
