Well dang! The company is indeed stopping having the product my doctors in three states have ordered as medically necessary for me! I’m very unhappy and not sure what to do next. 
I am in conversation with a national ombudsman as well as my insurer and have emailed my doctors in three states. This follows a national trend of discontinuing this vital product! The driver warned me of this when I saw him on Wednesday and sure enough I got a formal letter about this today.
