Jaydog, when you put on the adhesive and the wafer, make sure that you get a seal 100% all around the wafer, like a zip lock bag where you can hear, or feel, the two pieces "click" or lock, into place. You'll have a secure seal (bag to wafer) and practically no leaks. When you place the adhesive on your skin and wait for it to stick, put your hands over it for 30 seconds or so. This will warm the adhesive and you'll get a firmer stick on your skin, preventing leaks under the adhesive. My nurse taught me this. And, if you get a rash or itchy skin when you remove the adhesive (some people are very sensitive to the adhesive) put a very warm, moist towel on it and just rest for a minute. It will soothe your skin and give you a break.
Girlunky, your pea story made me laugh. It reminded me of a mushroom that shot out of my stoma, like something that blew out of a volcano.
