I guess that means the Amantadine isn’t helping as much as you’d like then? I’m on Modafinil and, although it’s not suddenly ‘cured’ fatigue, I do think it’s great. There’s days where it doesn’t seem to do anything, but that’s usually because of other factors, like the recent hot weather. But generally I don’t get so tired at work.
On the downside, it’s raised my blood pressure a lot and I’ve had to start taking pills to try & reduce it. If it doesn’t come back down then my neuro said she’ll stop prescribing it. I’ll be very sorry if that happens.
As your MS nurse has said, it’s generally not widely available. I’m fortunate here as my neuro fought hard to be able to prescribe it, so I think you’d need a neuro who’s willing to do it. It sounds like you’ll struggle where you are, but you should ask anyway.
