To be honest after doing pelvic exercises regularly I've never had any sort of leakage. I had close calls but no leakage. I try to do them every time I come from the toilet or before hitting the bed. Atleast twice a day. Also what I found is my pouch is empty when there's a blast of gas at the end of my visit. All the trapped gas once its out , relieves me for quite a few hours. If not I'll probably be hitting the toilet again soon. This sounds funny but thats how things are for me. And believe me the sound is pretty large too. The number of trips for me is proportional to the kind of food I had. When at work I fast for long. A big shake post workout helps me cover up for all calories I couldnt consume in the day. I just hate going too many times at work so I eat light breakfast and a late lunch.
