Insanity every other day?

Options
Hi all,

Hopefully this isn't too dumb a question, but has anyone done Insanity ever other day instead of daily? I started it last week, but have only managed to fit in the workouts every other day, for the most part. My schedule is crazy busy (single mom to 3, going to nicer with full time) and I don't always have the time (or I'm just so exhausted that I need sleep more than a workout). I imagine it means it will take longer for me to see results, obviously, but is it okay to do that way?

Thanks!
