Support belt time limit?

Andrea • 👧Dec '16, 🤰 May '19 🎉
So I finally got myself a belt to help support my back yesterday evening. I decided to sleep in it as well because it allowed me to lay without messing with a pillow for under my its almost 1pm the next day and I have yet to take it off......should I be using this in doses, or is it OK to wear around as much as I please?
