Lately, I've been feeling really sluggish. I don't know if its the heat or humidity (temp usually around 90 degrees with 80% humidity) or the new mileage level I'm at (around 75 mpw) but I have a feeling I have an iron deficiency. I've had this problem late into the cross country season last year, but I started taking a multivitamin and got over the problem. I'm still taking the multivitamin, but I'm thinking that my anemia may have returned because I'm feeling the same way I felt before I started taking the multivitamin. Can somebody tell me if they think my anemia has returned?
