@Jajakio, the entire recovery process IS really tiresome and tedious! Your feelings are shared by all of us, but it's good to let it out now and then, isn't it? We just can't dwell there; hah! No, we cannot. I don't think you are as evidenced by all that you are doing, and frankly, I think you are doing remarkably well for just 8 weeks post-op, so CoNgRaTuLaTiOnS! Seriously, pat yourself on the back! I certainly understand the Energy Drain theory, but some of the bone-tired, drop-dead exhaustion just has to come from poor sleeping, wouldn't you agree? Once we are sleeping *normally* again, everything improves, from knees to mood; pinkie swear!
I didn't achieve great sleep until I realized I needed to sleep on the memory foam mattress in our guest room. We have a latex bed in our room, which, under normal circumstances is very comfortable, but...not post-tkr. I slept on the softer memory foam bed for several weeks, sometimes with Mistah, sometimes with a dog or two, and sometimes alone. It was the answer to my "Beauty Rest," prayers and also to side-sleeping. At about 12 weeks, I was finally able to head back to the master bedroom, though, occasionally, we'll switch off to the memory foam bed just...because. I think what I'm trying to say here is *softer is better* when it comes to the new knee. If you don't have a memory foam bed in the house, you could possibly consider buying a topper, just for your side of the bed. You wouldn't even necessarily need a memory foam topper, possibly a feather bed topper would do the same. So, this is just a suggestion that really made my knee and my sleep ever so much better!
