I have be using John of Ohio formula and it worked for me. I rarely feel dizziness and my the stuffiness in my ears are gone most of the time. One of the items listed in John's formula is Cocculus Compositum that I used to purchase through the internet. Lately all the places that used to carry it have indicated that this product was discontinued. Vertigoheel an equivalent product is available but requires a Dr prescription. Does any one knows why Cocculas was discontinued? I found Cocculus Compositum vey effective fro dizziness.
