Hey Surfer, For the most part its rare that I can even smell the odor when it happens. Ive gotten familar with the look people give me when it comes on strong. Ive never had any type of std of any kind. Dont know about caniada (I guess i spelled it right...lol). I tend to stay away from crowds usually just incase I do start to smell. Im gonna look into the betaine and try that 1st just to see if its works. One of my friends think its all in my head because she does not smell it but I think its because she has just gotten used to it. If you come across any other useful info let me know plz. Take care!
