Is your doctor doing blood studies about iron? I had similar numbers to yours although I take HU 4x week. I also take iron supplements 1x day which improved my energy level. I have low iron but not anemic. The fatigue got better for me after being on HU for a year. My doctor does incremental dosing and started low and worked up to 4x week with HU. I also drink a lot of water as the HU makes me very thirsty. Hydration is good for the energy too. Take care!
