Sleep with maternity belt on

I'm about 33 weeks and my doc gave me a tip this week to sleep with my maternity belt on. I had never heard of this and would never have thought of it. It's helping with my rib soreness, soreness in my diaphragm, and the general feeling of being uncomfortable trying to sleep on my side and turn over and get out of bed. I wear it over a tank top to make it a bit more comfortable. Wanted to share in case anyone else could benefit from the advice!
