Caught a bad stomach bug (or food poisoning) while in Mexico. The locals said a flu bug was going around. I always carry ACV, Lugol's iodine, charcoal, oil of oregano, probiotics, and a host of other goodies just in case. Regurgitation (8 times was so violent), I thought I'd be carted off to the ER. The next day my entire body was terribly sore, even my eyes, teeth and fingernails hurt. I rubbed DMSO cream everywhere that hurt (no - didn't put in eyes! ) and it took away the soreness. Eyes still tender. Just remember to take OofO in the AM, and at night repopulate the good gut flora with probiotics.
