There seem to be quite a few people who have the exact same problem as you describe. I did a poll on the trimeth site (if you look in the "poll" section). I'm sure there are more out there than what responded on the poll so far. The "nickname" for trimeth is "fish odor syndrome." But I have read that this name is misleading because of the variable odors experienced, not just fish. I think there are a quite a few people with fecal odor in the trimeth group.
