My bowel moments are pretty regular. I run so I may have 2 or 3 a day. (I know it sounds gross!) I feel like it comes and goes because on somedays I may not get the usual reaction and on other days I can tell by the look on people's faces. No white coating, no nasal drip. Infact i use to have sinuses really bad as a kid until I started running. The only time I can smell myself is after I run for about 20 mins. Thats when I smell the fecal odor. Other than that, I can't.
