I agree with Huma, the OxyPowder is really very potent and when I have used it I could not stand more than four days once in a great while because I experienced what you are experiencing. It is also pulling out all your minerals so you want to replenish them very quickly. I know that it says it won't do this that or the other thing but I don't think that is entirely true. My minerals were so depleted taking it that I had a few times I blacked out. Take care and get some minerals in your system.
