I have found that medicated sleep isnt great sleep. natural, I am tired, let me lay down sleep is what really recharges my batteries. The less meds I take, the better I feel. Pain management will do PT and OT and relaxation and yoga and other stuff to help suppliment your routine and hopefully you can get more of what your body is supposed to do naturally.
If you cant walk, they sell those bike rider things that you can do while on the couch. Lift cans of soup and get those muscles burning. do streches or chair exercises. stretching out those muscles really helps cue them into the mode of releasing the toxins they hold onto. Lactic acid can cause all sorts of cramps.
I am hoping to find a better rhythmn than I have currently myself. I am just hoping to do it with less meds.
