It is difficult to answer your questions because it appears as though homeopathic remedies are being used like allopathic drugs by your homeopath.

If you take a remedy that is not required at the time, it may doing nothing or it may cause less desirable symptoms (provings), at the very least it does NOT stock pile in the body to be released when it is required, they do not work that way.

To answer your 2nd question, I believe it is the normal opinion of most on this board that taking many different remdies at the same time is dangerous and counter-productive.

Its also not normal practice to ping-pong between potencies like that.

I would suggest that you learn a little bit about homeopathy and talk to several different practitioners. In Canada we have very few actual homeopaths, rather many Naturalpaths that really only have limited training in the field of homeopathy.
