Anyone On Zinbryta?

Has anyone been taking Zinbryta? I was on Tecfidera and it was not working for me. I had previously taken avonex which also did not work. My Neuro doc put me on weekly 1g solumedrol infusions back in the summer and I had a major seizure during one of the infusions, so now steroids are out for me. The side effects of the Zinbryta have me really concerned. Anyone using that could share their experiences would be great! Thanks.
