Hi, i was just wondering if you ever got any useful information about this problem..i have just encountered the exact same thing except it was the day right before my period...i too threw up and had to go to the bathroom constantly (i also threw up some alka seltzer i took to try to ease the throwing up but it didn't work!)..today when i started my period i am no longer throwing up but it was really strange..i have been all raw for about a month and a half...i would appreciate any information you may have gotten..thanks for your time!
