You have gotten some good input up there. This place is wonderful for finding folks who have gone before and truly know what-is-what in this journey. I have learned more here than from any medical professional involved.
I am another one who is completely happy with my choice to have a permanent ileostomy. My life with my colon was being robbed from me, so I reclaimed my life and have never once looked back. I stole a phrase that I saw on the board, "my colon rejected me, so I am rejecting my colon" and it perfectly fits my thoughts. There is nothing I cannot do in my "new & improved" life and you will soon be saying the same thing.
You sound as though you have a deep faith and that will definately help get you through. After my first pre-op visit with my surgeon, I was a little discouraged. I had made up my mind that I wanted surgery, but my surgeon did what he had to do in telling me of a couple of complications I could encounter due to my particular set of circumstances [none of which happened, BTW ]
So, I came home from the visit kinda down, and prayed long and hard before going to sleep that night. I woke up the very next morning with the weight of the world off of my shoulders and a deep peace about surgery. I felt that God was telling me that I was to go ahead with surgery and He would take care of the outcome, which He did.
I am really hoping you find that your supplies will be covered under a different part of your plan, with your deductible. I have found some supplemental products on Ebay for cheap, but have not needed to purchase wafers or pouches as I stockpiled after my surgery, when my deductible had really, really, really been met. Best Buy Ostomy, Ostostore and Medical Mega might work for lower prices.
Oh my, all the samples--go for them !!! I have gotten so many samples from all the major companies. Coloplast, Convatec [my fave], Hollister, Cymed, Marlen & Dansac all sent me all kinds of stuff. Powder, paste, Eakin & Adapt & Coloplast seals, a belt, canvas carrying kits with scissors & mirrors [Convatec & Hollister], all for calling and asking. I did this prior to surgery as I had never even seen an ostomy appliance before and wanted to familiarize myself with the products. They were so generous, as they want your business. I asked for any products that they thought I might be needing on a regular basis.
Good luck with the surgery and you will be in my prayers
