Probably a few weeks I noticed a difference, but I’d say by 4 weeks it was more noticeable. At that time we went on a vacation and I felt great, continued to feel good through April and May. Still felt good in June even though the blood tests show my hemoglobin, and iron levels, are dropping again, so therefore getting another infusion. I still don’t feel that bad. Also, they have not been able to determine why this is happening so far, I’m waiting for some tests to come back.
