We have a nonstop talker too. DS8 has been talking nonstop since he could talk! Which was early... I am kind of chatty myself, so I can sort of understand his need to talk, especially after school, where he's spent the day being quiet. He does have daily homework of 30 minutes of reading, which is a great break. I try to keep him supplied with really good books so he goes beyond the 30 minutes. (even though he could read well early on, for the most part he would read only if it was a school assignment.)
A not very healthful suggestion -- ring pops! They work.
