The main difference between pre and post op is that I use a box of man-sized tissues every three days rather than one and I use artificial saliva. I get days that I'm mopping up constantly and times when my mouth dries up completely. If your objection to have it done to you because it's permanent, let me ask you; how long is permanent when you're living with MND? Every second, minute and hour are priceless so spend them wisely.
