I'm so sorry about your fall Barb. It's happened to me several times but not in awhile (knock on fake wood).

Once I was sick on the floor and had to yell for DH about ten times before he work up.

I think it's a good idea to cut down on some of the meds a bit. Also, maybe keep a cordless phone handy at night?

I also think the idea of the rollator just for nighttime use is a good idea.
