Yes, thank you, I have tried all the over-the-counter meds and found them an entire waste of my money. I did try the Activa and there were no noticeable changes. Maybe due to the lactose intollerance. My gas is also sometimes trapped. When I was younger my parents took me to the hospital a couple of times, because the severe sharp pains and my crying made them think it was a possible appendicitis attack. I almost prefer the painful times to the smelly gas! I've been in large crowds before and was unable to hold my gas. You can imagine my complete and horrible embarassement. I actually came close to passing out because of one I experienced at a concert. Everyone standing behind me, including my then boyfriend backed way up all at once. Whenever I get up in the mornings, my entire bedroom smells toxic and I'm not entirely sure that it is not! Obviously I am desparate.
As a gas tooting old timer, I can relate to your predicament. This is what I have discovered in my 20 plus years with the always unpredictable IBS.
When the gas is that toxic, it is usually a symptom of conjested bowels and a proliferation of bad bacteria that results from improper transit and elimination. In other words, ya ain't poopin' properly or enough and there's probably excess fermented waste hanging around your colon. These days, I still suffer from viscous bouts with gas, but they don't smell. It's mainly air trapped in the colon. As long as I am having BM's with some regularity, the odor is practically non-existant. The moment I "back-up", watch out, gas mask time!
So, I guess the question would be how are your bowels moving? If you are experiencing frequent C, that could be your problem. For me, even one day of C will cause noxious gas. I have found that food is not the culprit. As long as the food keeps moving out and doesn't hang around the colon long enough to ferment the bad bacteria, I can eat almost anything.
