There are so many challenges we face with Esophageal Cancer. If what I have been through can in any way help someone else I consider that a blessing.
We also an adjustable bed but I found that I was continously sliding down the bed which gave too many nights with reflux happening. Since this is very uncomfortable and dangerous for our lungs I decided to go back to the wedge. The difference is I went on line and found a wedge that was larger than the 24"×24"×12" one I was given by the surgeon. This one is 31" wide by 33" long and 12" deep. By being wider I don't fall off, by being longer I don't slide down. I like it so much I bought another for our camp so sleeping is the same in both places, continuity is important with all the changes we face.
Eating will also be much different after surgery. The will probably give you a list of what you can and can not eat. What I have found two years post surgery is you body will quickly tell you what you can eat and even quicker what you can't. Don't get discouraged though because you will find a balance in your journey. I have lost over 80 pounds since my journey began but have maintained my current weight for about a year.
You will probably have other times after surgery that will be very tough but it is worth it .
