No, haha - I'm actually one of the few people I know who has no Stomach, or GI issues Ever. Last time I was sick was 2 years ago with some mild vomiting for a few hours. Before that no sickness was several years. I eat very well and am actually a Holistic chef (just mentioning that due to my educated choices of healthy foods-yes I practice what I preach) I'm not a meat eater. I'm almost 40 and people tell me I look 25 - I'm male. I've done yearly intensive cleanses and have not once passed large form worms or flukes. - I am planning on getting a Doctor to look at this just to see if they take it seriously - and I'm in Canada, Vancouver Island.
