I had to take 6 cycles of the same chemo for Ovarian Cancer in 2007. I still have some neuropathy in the balls of the feet. For me, from what I understood when I had each cycle: the longer lasting effects were cumulative (they became more so with each cycle) The shorter term effects seemed to be only the worse at the beginning. Also it seemed to me that the worse effects were in the first 14 days of the infusion of each chemo. The next 7 days the body felt better, less toxic feeling and under less of an attack. Then I would have the next treatment. So in general by the time two weeks had passed most of the previous treatment had left the body. However it took several months for hair to grow back. And of course it took a long time for my fingernails to look and feel normal again. My last chemo was two days before Thanksgiving Day in Nov '07 but it took till Christmas for me to really enjoy food again. By April '08 I needed a haircut. I did use B vitamins daily, a 5000mcg Biotin, 200mg CoQ-10, and an herb known for helping nails and hair, Horsetail Shavegrass. They seemed to help. The CoQ-10 was to help with energy and to help protect the muscles and heart tissue.
