Not much to be said that hasn't already been said.
I was lucky with my episode that I didn't even have a heart attack, so no damage, but a triple bypass.
You hang in there Joe, and you are in my prayers. Changing your diet isn't easy at first, but can be done. I had to do it first for diabetes, then for my heart. I understand about the portions. When my doctor first gave me the portions when my diabetes was diagnosed, I asked her why she didn't just go ahead and shoot me. Who could live on that? But you can do it. Believe it or not, slowing down and chewing until there isn't anything solid in your mouth helps. It seems it takes a while for our stomach to comvince our brain that all is well below. And, it gives more time to enjoy the food. And enjoy you still can. It may not seem like it at first, but the enjoyment will still be there, and more importantly, you will be there to enjoy it.
However you choose to do it, stay with it and stay healthy. God bless and as you can tell, you have a lot of folks, not only where you are, but here on the forum that are pulling for you.
Again, stay healty, take it easy, and God bless.
