Need Extra Batteries???

I recently read, "Keep a stash of extra batteries." They were referring to keeping extra batteries in case of an emergency. I often think that "MY" batteries run down.

Fibromyalgia/Chronic Fatigue depleats your energy faster than you can blink. Well, maybe not that fast, but faster than most people could understand. Not only is your energy depleted, but because of a malfunction of the central nervous system, the pain is unbearable. You must learn what works for you to regain your strength and what takes the edge off your pain. For me, rest replenishes my physical and emotional strength. Prescription medication helps with my pain.

So...do you have an endless supply of batteries? When you are run down, exhausted, with no strength to continue, how do you replenish your energy?
