I have had similar challenges with chocking, swallowing and lack of taste and smell. I was refered to a speech language pathologist who gave me excercises to help strengthen muscles as well as tips. Try to eat smaller bites and have liquids close. Eat without distractions and facing forward. I find if I look sideways (toward someone else) I will have greater risk of choking. I use « Pür Gum and Mints » as there is no sugar nor chemical sweetener to help with saliva as my issue is that I do not produce enough saliva and the food gets stuck going down.
As for the lack of taste, I tend to add herbs and spices that will enhance the taste. Mint helps as well to enhance taste and is often suggested for cancer patients who lose taste with treatments.
