Turns out I was just iron deficient
I’ve struggled with chronic fatigue and idiopathic hypersomnia since I was a teen. My labs came back “normal” (20 ng/mL) but one day I asked my doctor if I could take iron supplements to get to optimal levels and she said I could. I not only have more energy, but I am actually happier and more motivated. Obviously, this isn’t going to apply to everyone with chronic fatigue, but it’s crazy how long I’ve been dealing with this when the answer was so straightforward.
