This is a difficult one. The similimum (your exact constitutional remedy) would address all your problems but this is very difficult to find these days because of all the pollution , vaccines,stress etc we subject ourselves to. The remedy that gave the aggravation was probably a similar remedy and may have brought out the next remedy more clearly. As for the one that you had the most improvement from I would have repeated it at the same potency to see if that improvement could be replicated. If not or if it was short lived again I would have gone up a potency before deciding on another remedy.

If a well chosen remedy still fails to hold I would then be looking for a miasmic remedy which would alleviate a blockage after which the remedy may well work .
Have your energy levels improved at all while on homeopathic treatment.
