Hi "3-weeks post-op"
You and I are both on same schedule of recovery. Like you, I was flabbergasted at the weakness in my body after surgery. I actually work out 4-5 times a week (at least before the surgery) but now just getting up in the morning, getting dressed, etc. seems to be a gargantuan task. I actually went with my sister to run some errands yesterday and couldn't WAIT to get home. 3 short hours out of the house had transformed me into a raving lunatic birch (kinda funny actually) but made me realize that I don't really want to socialize or go out in public for another few weeks at least. Between the pain meds, the sleep deprivation and my my body's refusal to do anything that requires energy, the public at large should be protected from me until I feel human again. That's the thing about surgeries, medications, illnesses, etc. They all completely knock me off my grasp of sanity because I am soo NOT myself when I'm recovering from any of the above-referenced events.
I do take Melatonin and it works great for me. Meditation helps keep me on somewhat of an tranquil emotional path.
Also, not as grumpy now with the advent of Spring in the air.
Stay in touch and let me know how you're doing (or not doing, ha). It's good for me to talk to others on this site that are on this same chronological recovery timeline that I am...
