Not sure what advice you’re wanting, really. This is not a decision anyone else can make for you, but I do know that whatever you decide, the person who has to be comfortable with it is you. Inviting others to vote on it won’t make any difference, if you’re not doing what you feel is right for you.
I’ve always declined DMDs - controversially, in the eyes of some. Though I must stress, I’ve never defied medical advice - my choice was with my neuro’s backing, though he never tried to influence me one way or the other. Only after I’d said I didn’t want them did he admit that would have been his choice too. So I left feeling a lot better, and that I wasn’t doing anything he thought reckless or silly.
I do realise it was a bit of a gamble, but all we can ever do in these circumstances is what we feel is right at the time. Others may think it’s a no-brainer to be on them, but for me it wasn’t, and three years later, I’ve no regrets. I feel that even if I were to have a big relapse now, I’ve still had a pretty good run, and there’s no guarantee I wouldn’t have had it, even if I was on DMDs, as we know they don’t stop all of them.
Why not have a chat with your neuro? You might be surprised to find that, like mine, he doesn’t believe they’re always right for everyone. It’s a balancing act! If he agrees the case is not that strong for you, you might have a clearer conscience about giving it a miss. Alternatively, if he makes clear his advice is to take them, that’s something to think very hard about.
Personally, I don’t have a “regime” I put my faith in instead. I do religiously take Vitamin D, which I’m confident plays a part - and which was endorsed on a recent visit to a different neuro (first time in three years anyone mentioned I should be supplementing - good job I already was). I don’t find the evidence for diet and other supplements terribly convincing, although I do take combined capsules of acetyl-l-carnitine and alpha lipoic acid, because I once read a study that suggested these showed some promise. They are very expensive though, and I don’t think the evidence is strong enough to suggest everyone rushes out and buys them. Just a personal foible of mine.
Other than that, I do try to stay as active as possible. I don’t have a dedicated workout regime, but I do walk a lot more now than I did when I was well. A couple of years ago, I got scared when I could not walk much further than the post office (about half a mile). By continually challenging my limits, I’m now up to 3-4 miles, including semi-rough terrain (stiles, tree-stumps etc.) I do find that if I don’t keep up the practice, my range drops again quite rapidly, so I have to keep teaching my body how to do it, otherwise it just gives up. I’ve no plans, at the moment, to try to take things beyond four miles, as that’s much further than I ever did when I was well. At 47, with MS, I think it’s enough!
