I just want to say if your a person who enjoys taste please don't try this. I did all of these horrible steps endured the disgusting tastes and for what? Only difference is noticed was my teeth got overly sensitive and I've never had that problem before.
Idk how so many people like this brand I hate it! Doesn't feel like it does anything at all like could have used water and it would be more useful. It angered me I was mislead into thinking this would be such a good product.
