Have You Often Hit 0 Slots As Full Caster?

Just a curiousity of sorts, wondering how often y'all's full caster characters have managed to cast themselves all the way down to having no spellslots left to spend.

Never happened to you? Only occasional? Frequent even for ya even maybe?

I like playing casters and it will occasionally happen but not too often.  I've made the mistake in the past of 'holding back' and having slots left when I really should have used them.  I've made that mistake on BG3 as well.  

One of the things I like about 5e and 5.5e is the scaling cantrips.  So even if you run dry on slots you still have viable options.
