Is there a way for you to stay downstairs for a while at home? My friend had both done at once and she did really well with it. She is 2 years older than me and had it done right before Christmas. My MIL did one at a time.
I live in a mid century modern home, first level is kitchen, dining room and half bath. Living room on it’s own level. Top level is full bath and bedrooms. I will have to do stairs. No way I can manage without it. Only good thing is that they are half flights...only 6-8 stairs going in any direction.
