Looking for your 4X whitener. Cannot find any store. Have you stopped producing the 4X whitener?

I have used this product for several years with great results. I noticed the packaging has changed and something must have changed with the rinse because it now burns my tongue and lips and made welts on the bottom of my tongue. As soon as I stopped using it my problems went away so I know it was the rinse. I am disappointed as I have been a loyal user for years. I now have to switch to a different product.
