I had the same side effects when I ate a bag of nuts (it was either brazil nuts or walnuts - i cant remember now) and a bag of seeds (pumpkin or some other seed) - I bought them for their anti- parasite qualities after reading something on the internet. I had the same very acute side effects- the extemely foul odur belching and also extreme diarrhea - in fact the worst diarrhea I have ever experienced (didnt stop for several days). needless to say i stopped immediately - but i did wonder if it was actually doing me good or bad - i would be interested to hear from anyone else because if it was actually doing me good i might perhaps try to tolerate the side effects for a cure?
thanks,
