It's not easy. The things I do is to pace and to take time to rest every day.

I found out my low energy was mostly from sleep apnea and low vitamin d. Improving those has helped quite a bit.

I've found exercise helps me but I'm usually fairly active on work days and walk 4 to 5 miles. I've found too much exercise make me miserable along with laying around doing nothing. Have to find a happy median for me
