Sometimes I can have gas that doesn't smell a bit and sometimes I can have gas that will make you tear up!!! All comes down to what I eat and how my DS insides process it.
I poop at least once a day and like clockwork. Everyone morning I poop, and maybe again that day, usually depending on what I ate the day before. I wouldn't call it diarrhea by any means, just a softer...easier poop. And constipation can happen too from the vitamins, so you need to find a good balance between food, vites, fiber and fat. I was a very regular once a dayer prior to my DS, so I might go a little more frequently now.
And that body odor thing is a line of crap! I probably smell better now then I ever did before my DS, since I quit smoking and rarely perspire. Whoever came up with that one is probably just jealous cause they gained all their weight back LOL
