Hi, Pamela. Congratulations on your weight loss.
You probably have already heard about courtesy flushes, but I'm afraid once you drop the stink bomb, the stench spreads out very fast, indeed. You may always want to carry Ozium smoke and odor eliminator. I spritz into and around the toilet before I start.
My stuff was so bad that my nieces and nephews named it Zorg for the alien that crawled out of my rectum and died, after overhearing my sister say the stench "was not of this world."
Our "zorgs" are caused by malabsorption. You need to look first at a probiotic. Another duodenal switch forum recommended Primal Defense Ultra by Garden of Life. You should boost its power by a good prebiotic. I get one from Vitamin Shoppe called Nutra Flora FOS.
I had researched internal deodorants on the internet and learned that alfalfa and chlorophyll would work, but they only helped a little. After Zorg kept setting off the carbon monoxide in the travel trailer of a friend I was visiting, I went to the vitamin store to also add parsley to see if that would work and told the manager about my problem. He told me to get activated charcoal tablets.
I have found that this protocol works very well for me. I don't set off alarms anymore and if I'm in the middle of something in a public restroom, people still come in and do their business rather than cough, choke and quickly exit, looking for another place to do their business.
Devrom has been recommended, but I won't go there if I can get natural supplements.
Hope this helps.
