i don't know how long it's been since your surgery, but like sigmachi said, the first 6 weeks, you need to be kind of careful with your diet, stay away from fresh fruits and veggies, stringy meats and anything that might give you bad gas, like spicy foods, or sodas.
also at first, the output is very watery, and there is lots of it and lots of gas.
that pressure feeling, i had it a lot at first. something that will help is to use something that will hold your bag to you, so that it isn't hanging down. i still sometimes have that feeling if i have really thick output. if you have it a logn time and nothing comes out that could be a blockage, but if you are having output don't worry.
after 6 weeks, start adding stuff slowly, like have a small bit of broccoli and see what happens, then try somethign spicy and see what happens. the thing about soda is it will give you gas, and it doesn't hydrate you, and you have to be very careful wtih that, drink WATER, that sugary stuff (juice too) doesn't help that much.
after about 3 or 4 months out you should be eating whatever. Im 4 years out, and today i ate (don't fall over this is crazy) some applesauce, jelly bread, popcorn, half a hotdog, half a hamburger, chips and dip, ice cream and cake, some ham and some mush. i usually only drink water, i did have a few sips of coke today though.
and you can still drink, once you get off the pain meds, and the gas lessens. but since we get dehydrated so easily,drink water too. like i usually have a drink and a glass of water, and drink both.
im not exactlly sure what you mean about your wafer problem, i just use the hollister new image, for now, and put the wafer on, pressit for a minute, snap the bag on, stand up, fix the bag the way i want it, use the hair dryer, and put on my sure seal. you do need to press on the wafer a bit, a hair dryer helps, but if your wound is still healing don't use that.
