I have one and it does help. I didn't use it this time because I'm here alone and was concerned that I might get stuck in it since I was barely able to move.
As wife #3, I can say with full confidence that third times the charm! DH was married for 2 years the first time and 7 years the second time. We are heading for our 11th anniversary so he had already beat the odds this time. I occasionally remind him that had he made a different choice all those years ago when we dated while I was in high school, he could have saved himself lots of headaches....instead it took him 15 years to figure out that I was really who he wanted to be married to!!
I loved my first 2 wives, the third was evil personified!
So I'm at "three strikes and yer out" status. Unless I go into extra innings...
