Your Dad's respnse sounds like mine. When I went to the higher does with Dr Raza I felt terrible so I opted out but my trans fusion frequency never got a whole lot better. I was 4-5 weeks then all of a sudden I went to two weeks. So I went to a Dr Voorhees at UNC Chapel Hill, NC and he did a bone biopsy and then put me on Dacogen. My results to date on Dacogen have been fantastic. If you want call me at 910-791-6745 and I will fill you in on the details.
