I know you've mentioned your colostomy bag stinking before. I use a closed one-piece by Holister and it is odor-free 95% of the time. Oddly, I tried a Coloplast bag recently and the odor was immediately noticeable. So your bag type may play a roll. Before the Holister I also took Devrom daily to help with odor, and took a daily pro-biotic and enzyeme to help with digestion. Just some tips on what I do.
