Usually, especially when packing a lot...Nothing too dangerous, but I try to fight off the reflex as long as I can, as I usually end up swallowing air.

When I pack really full, I cannot hold all the air in my lungs, but I let some of it fill my mouth and cheeks. I'm usually fine until the point where I push this air back into the lungs (around 3 or 4 minutes). After that I get the swallowing reflex. I guess it has something to do with the difference in pressure or something (as long as mouth and lungs are equal I'm ok). Or somehow moving the muscles and parts in the throat to make the "transfer" possible stimulate it. Dunno...
