All good answers, but I want to add if you're talking about days in a row I have found it loses its effectiveness. I think it's one of those that tolerance builds up quickly. So I try to use it as a last resort if nothing else eases symptoms. The effectiveness comes back if you leave it alone for a bit tho, like for me a few days without it and it works again.
