Connie, I am happy that Jerry is doing well. There are mixed reports here about how long one might see improvement. Some say at two years you get what you got. I can tell you that some (me) continue to improve well after even four years. In fact just today I was eating something that I popped into my mouth before getting the obligatory glass of water. Usually this causes a bit of panic to set in but this time I had enough spit to make do!
