In combination with other suggestions here, is your neuro checking the med levels? It may be too low, which is why they're not working. I also think a month is too short (excluding bad reactions). I think checking levels and the idea of raising or lowering dosage (too much may do this, too) should be done.

Hang in there!!

PS: Trying a lot of meds (we typically call it the "Labrat Phase") is pretty normal and most of us have gone through it.
PSS: Welcome!!
