Dkelban,
I understand. I can read, talk on the phone, watch LC videos, for 1 to 1 1/2hours… then, the fatigue starts to creep in. The best solution for me is a 30 minute nap. I used to balk at the thought of lying down during the day, but it makes the difference on how the day plays out.
I am not crazy about exercise, but 3 months into this, I see and feel my body lose conditioning. So I force myself to do the exercises my physical therapist shows me. And…. take another rest. No sleep, just meditate.
