I rarely get a leg jerk when sleeping. Mainly when sitting down.

It's dif per person, I have a little bit of say restless leg syndrome so they call it, now and then, but not often but does, I'm not on that med here, but I am on divaprolex and levetiracetam, it may have something to do with my symptoms of my leg movement and symptoms of it, my opinion

I get leg jerks anytime I sit and try to relax. Usually the right one.

I'm only on Keppra, but been having occasional leg jerks for years

I do not have knee jerks at night, but then again I do not take XCopri.
