2Nd Time I've Had This Illness In 2 Weeks, Starts

2Nd time I've had this illness in 2 weeks, starts with cramping and diarreah, then nausea and vomiting. Severe nausea stomach spasms continuously and vomiting about once each hour. Spasms don't go away throughout the term which lasts about 14 hours and then suddenly it's all gone. I only tried to drink water and my vomit was like pea green.tim
