I STARTED THROWING UP TUESDAY MORNING, EVERY HALF HOUR, AND THEN HAVING DIAHRREA; I GOT SO WEAK AND MY HEADWAS HURTING (ACTUALLY MY HEAD HAD BEEN HURTING FOR ABOUT TWO DAYS) ALSO, THE THROW UP AND BOWEL WAS YELLOW. SINCE THEN, THURSDAY AND TODAY (FRIDAY), I FEEL MUCH BETTER THAN I DID; I'VE BEEN ABLE TO EAT SOME CHICHEN BROTH, THEN EASED INTO SOME CHICKEN NOODLE SOUP, DRANK SOME GINGER ALE AND WATER, BECAUSE I'VE BEEN VERY THIRSTY. SO FAR, I HAVE NOT THROW UP OR HAD DIAHRREA SINCE TUESDAY. I CALLED MY PRIMARY CARE DOCTOR'S OFFICE, AND THEY HAD NO APPOINTMENTS TODAY, BUT THEY PUT ME ON THE CANCELLATION LIST; NOT ONE HAS CALLED. LIKE I SAID I FEEL MUCH BETTER THAN I DID; DO YOU THINK I SHOULD GO TO ONE OF THE WALGREENS LITTLE CLINICS, OR JUST PLAY IT BY EAR?
