Just a quick note to say hi! I read your post, have several dysautonomias, and vasovegal issues. It is the vasovegal that might be bothering you after a meal.
I stumbled accross your email and want to let you know that my doctor put me on a powder called PREVALITE. It comes in a packet and I mix it every morning with a couple of ounces of water and some juice. I can eat anything and it has stopped the need to go to the bathroom. It is wonderful. Maybe once in 5 months I might have the good old dumping syndrom hit then it is gone again. No pain, no problem with anything I eat, please ask your doctor to let you try this. It is 5.5 grams of powder. It looks like it is for cholesterol but it works. Good Luck to You.
