Tbra is right -- most, not all, of the folks posting here have or are still having some complications with their current pouching system, still trying to find that one that fits them the best, so they are here asking questions and learning.
I've had my ileo for soon to be 24 years and I have just recently switched from a paste to the Eakin Seals to use with my wafer. I have been pretty lucky. With the Eakin Seals, I get 7 days wear time out of it, usually year round.
When I get the itchies, I know that it is time to change the wafer. Sometimes, especially if it is like the night before my "morning" change, I rinse my pouch out really well with cool water making sure to rinse well around the stoma, and that usually calms the "itchies" til morning. That is the only skin issue I have, and that is just my warning to get it changed.
Try not to get too nervous about this decision. You will be fine. After all, you have quite a few experienced veterans here on this forum that can help you out. And if we cannot, we certainly let you know when you should seek help from an ostomy nurse (ET - enterostomal therapy nurse). Please ask any and ALL questions you may have.
I wish you the best and know that the folks here on this forum are incredibly helpful and compassionate.
