I was having a BT every day in hospital (I didn't get a transfusion till day 6 because they wanted to see how I coped without one first - BIG mistake, I should have asked for it a lot sooner) and then after the transfusion I had a BT done at the 6wk check which showed my levels were normal again. All I took was Fefol (folate and iron tablets) each day for a month and made sure I ate loads of leafy greens and red meat etc.
