Our garage door goes down but then goes back up again. I know how to
adjust the down force and seem to have to do that regularly.

Now even that doesn't seem to help.

One other clue about the door. When it gets about half-way down it is
no longer moving smoothly but jerks, jerks, jerks it's way down.

Any suggestions?

Check the gears in the head unit. They are plastic and are probably worn
or missing teeth.
