How often do you use it?

So I've just started using tazarotene and been applying it every 3 days. I don't see any signs of irritation and I have a pretty solid hydrating/barrier repairing routine in the AM. I have been using adapalene and tret for one year prior to switching, but had a two weeks pause before taz due to vacation.

My question is, how often did you use it at the beginning and how long did it take you to up to everyday usage or every other day?
