I think your questions and the newly raised questions might best be answered by your homeopath whom you obviously have a repoire with.

Its quite different to take a bunch of different remedies at once vs take many different remedies for different complaints as the case progresses. I don't think its entirely clear in your case.

I do however feel that the potency is an issue. As Hans has said it requires a lot of study (5th & 6th organon, Kent, Boenninghausen etc) and understanding, that I constantly seek advice about myself, so I'll leave it at that.

I'm sorry I'm not much help, I know how frustrating it can be to seek a simple answer to a seemingly simple question, but it really is much more complicated than that.
