I been trying for years myself. It makes sense because I was told I was lactose intolerance years ago but b/c I had no symptoms I continued eating dairy products without enzymes. Finally my odor was specifically sour milk and rotten eggs so I connected this to diary products. Than I found out I had ulcers. I took the dairy enzymes and the prescription drug for ulcers and now I am 100% odor free. With enzymes costing only $15.00 its well worth the try. Please try. How long u had this problem? I had so many theories myself.
