Hi - I know the feeling. I get the same way and its called Social Anxiety Disorder and when you do get stressed, you do smell more. If you can control the anxiety you can control the odor. It is great that the probiotics work. One time, I did smell like a public restroom too and I final went and had a colonics - so it is like a very in-depth enema. It cleansed everything and the public restroom smell went away. Here is a website that explains what happens http://highcolonic.org/
I only use the open system. Sometimes you have to go every few months if you have problems eliminating. Also, you might want to start using a body wash called Sebamed http://www.sebamed.com/.
it is expensive, but it helpful with keeping the ph of the skin right. it is really helped in the vaginal and buttocks area for me! they also have a feminine wash that is soooooo much better than the stuff you buy in the store, but again it is super expensive. they make one for women who are going through menopause and women who are not. http://www.sebamed.com/229.html
