I have a bad IBS, very bad due to stressful life. What made my life worst and difficult to live with is leakage of gas from my guts without farting if I have minimal stomach troubles and as a result it ruined my "professional" career long time ago and my life in general as I became anti social (to avoid embarrassments). I tried everything possible to overcome this problem, taking mixture of antidepressants and good diet helped a lot, but haven't eliminated the problem completely. I spent money on expensive underwear, everything you see on amazon to overcome the smell, I tried it and they all failed. These capsules made all the difference to me, even when I do "number #2" in the bathroom nothing smells :) I take 2 to 3 pills every meal daily, depends on size of the meal, but I do not exceed 8 pills a day as prescribed (I avoid sugar, wheat, milk, beans & caffeine). I try to limit myself to having two main meals a day, morning, just a snack will do.
