I'm so happy that has helped you! I know many members like those. I had a problem with it because I couldn't roll over. I sunk in it and was pulling my back muscles to get out of bed. BUT I do have a huge hernia that makes my body "unbalanced" so that could be causing some of my problem.
But, I did find something else....a fiber bed. It's like a feather bed but made of material that you can wash. I got mine at Bed, Bath, and Beyond. I have a pillow top mattress, a foam egg crate on top of that, and my fiber bed on top of that! I'm comfy!
Alaska? Fibromyalgia? I sure don't know how you manage. You must be a very strong person!
