I had headaches when I stopped taking Betaseron, but I was under extreme stress, and my liver function tests were off the charts. I was nauseous but not sure whether it was withdrawl or simply detox to get the stuff out of my system, as my system hated the stuff.
It could also be stress related, as stress is a huge trigger for MS events.
I hope you feel better.
I am currently not taking any meds to control MS. I failed off Beta, failed off Copaxone and am simply too scared to try Tysabri. The new pill also comes with some risks, and since I tend to be over reactive to all of the drugs they try me on, I have decided to go bareback.
I hope you find some answers.
