I had been on 4.5, went down to 4 then I came off at xmas time and didn't go back on till March.

Because I was off for a while, I went back to 1mg for 2 weeks, 1.5 for 1 week, 2 for 1 week, and now i'm on 2.5. I plan to go up to 3 and stop there for a while. The lower the dose the better. I'll probably stay at 3 for a month and see if I notice less inflammation. Probably won't be long enough to tell but I think 3.5 or 4 will be the highest I go this time around.

It seems you can't tell if it's helping until you go off. It's April and I was off for 3 months. It took that long for me to facepalm and say "oh, i'm hurting more. duh, I should maybe go back on LDN." So, now it will be a while again. I plan to be on for life. Going off at xmas is kind of a long, not smartest, story.
