It can make a big difference for people in the beginning, and they do become accustomed to the change fairly quickly. That's why I always try to remember to tell people to write down their symptoms before they go off whatever they are on . . . and as they go along once they are on LDN too.
We do lose sight . . .
But, you CAN always test it, if you wonder if it is helping much ...

Like Marion, you might find out pretty quickly. I don't think you would be taking a risk of a relapse right away or anything, but at least you would see how much it is helping for symptoms.
Do you have a track record for relapses you can look back on, from when you used Beta? How about a symptom journal, or information on this site that you can look back at? We do have our ups and downs on LDN too ... but if you haven't had a relapse that has added to your overall disability, I'd say you are still on track.
