Thanks for all the responses, you guys have been very helpful.

The decision has been made. I'm taking 3mg tonight and will report back in the morning if I had any reaction to it (meaning if I have any "bad" reactions to LDN). Thankfully, I had no reaction to the 1.5mg, so hopefully 3mg will be same).

EDIT: Erika, are you only taking LDN or other MS drugs as well? Sorry if you already answered this in the past recently, I don't recall.
