My sulfate levels are high but I don't smell right now but my son does. I have more problems with abdominal discomfort than smell. I too have problems with CFS and Gluten. We now think we know what's going on. Please check out this web site from Dr. Amy Yasko this information is making a positive change in my family's life. http://www.dramyyasko.com/resources/webisodes/methylation-mutations/
Sounds like you might have the same Genetic mutations(CBS and/ or BHMT) as myself that cause regular animal protein and B-6 to stimulate the sulfate pathway to much. You may want to look into this. Doctor's made me worse by recommending me to eat a lot more protein before I found Yasko's information. Right now we are eating no animal protein, limiting B-6, gluten free, almost dairy free, and we are avoiding Sulfur rich foods. Not much to eat right no but I feel better and my sulfur levels are going down. We(myself and 2 kids) I gave them these crappy genetics. Here is one other site that was very helpful.
