When I was on Copaxone and had an insurance change my MS Specialist/Researcher Neuro said, I could be without "C" for 5 months and still begin again without starting over. He felt it stayed in the body for that long, in the lymph nodes.
I got approved right away again, so it wasn't an issue, but that was his medical opinion.
Maybe three months without "C" is not that bad for most people missj. Sorry it was for you.
PwMS could ask their Neuro if they want to get into a Clinical trial. Others may never have tried "C" yet, and want to. It isn't a very big trial. I thought they did one like this before.
I would like to see a trial of Estrogen alone, but Teva would not support that.
