I kind of like the expression in the topic. Hiccups and palps really seem to have a few things in common:

1. The vagus nerve is involved in triggering both.

2. Neither of the two are dangerous.

3. They both seem to come almost "out of the blue".

4. Both can go on for hours.

5. AND: Maybe some of the "tricks" you can use to make hiccups stop, can be used to stop palps? (Holding breath 30 seconds, drinking a big glass of water very slowly ...)

Maybe it'd be worth experimenting a bit with "5". Or?

Have a nice weekend.
