I hear BG-12 is much safer to take but isnt FDA approved yet. I would try that one, I told neuro put me on LDN until BG-12 comes out, but now he wants an office visit. I know what that means.... he will badger me until I give in to aubagio. I dont like this. My dh said I better get on some MS med or I could lose my SSDI. Im so confused and upset by everything, my heads spinning.
