5 years out for me. Also high platelets and high red blood cells. Testing for cancer, but keep telling oncologist hematologist that I never had issues since covid. Hydrea? Never heard of that treatment. Glad it's helping you! No energy, short of breath all the time. My old self is gone. Still working full-time as no choice, but hard to do ADLs like laundry and can no longer vacuum or do any "heavy" cleaning. Stairs are difficult. Take care, everyone.
