Beware.   Orally taking DMSO caused my sweat to stink like semi fresh oysters.  I didn't notice it so it must've come on gradually. This happened  twice (100 percent)  so I threw it out.  After exerting myself and sweating a bit I as in a car with some people an they all were complaining about this almost fishy smell. My Wife also smelled it later that day.   I tried again with half the amount (I was doing an elemicin preparation).  Still stink up

Any room I was in.

I read many similar reports onlIne.
