I smell sulfur

A couple times in the last month, I've gone to a mineral hot springs. The springs have high sulfur content. Not surprisingly, I came home smelling like sulfur because I dipped my hair in it. I took a gallon of fresh hotspring water home, and drank it for a week. I also take MSM; I have been taking it for six months. The mystery is this... ever since I started going to the hotsprings, I smell sulfur almost all the time. I smell it in my car, in my sweat, in my hair. I just smell sulfur!! Naturally, I've showered plenty of times since I went to the hotsprings. What's going on? Why do I smell it all the time? Is there so much in my system that it's coming out my pours?
Does anyone have any thoughts?
