When I was on tysbri felt very well about two days after infusion and at last few days of month would know was due infusion because tiredness would be there. The reason I stopped was feeling good stopped and back then there were more risks attached to tysbri. There is great news about positive results for cure it will come we just have to keep well and don’t let it get to you. Bound to be so confused with new diagnosis of ms but you will find a way to live with it and find treatment for your it’s a lot of trial and error but you can get used to it. Just keep on trying there will be bad days but they pass its up to you once you keep positive. Ms treatments are improving. If one doesn’t work try other one.
