Ziposia: Yes or No?

Two years ago I was taking Ziposia and I thought everything was good. I felt great and I had energy to return to school and finally get Mr BBA. Then I switched insurance and had to find a new Neurologist. This one ordered bloodwork and mri. MRI was great, no new lesions, bloodwork showed a huge problem. My wbcs had dropped below 300. My question is for those who are on or were, did your wbcs drop like mine did?
