you should know me well enough by now to know I prefer long answers.
So, I do understand the work out schedule now.
Yep, sleeping alone is very nice. When we were on Sabbatical, we had 2 twin beds on the floor, next to each other but not quite touching. Best sleep we have ever had as a couple. we snuggled on the one I slept on, then when we were ready to sleep he rolled over onto his twin. That bedroom also had a VERY loud fan. We called it the turbo fan! Our spare bed is the 2 twins set on box springs, but so that it feels like a king I have a layer of the egg crate foam on it, a fairly thin layer of memory foam (2" at the most), and a featherbed topped cover sheet (all from Target) and it has the same effect. Everyone who sleeps in that bed oversleeps. I think having the 2 mattresses keeps the partner's movements contained. Worth considering.
