We'll be right here - "anything" IS going to happen! You prepped good and chugged down a 'warrior size' first flush concoction. 'Hope you've got a colander, cuz methinks you're definitely going to "yield big"!
However, if you DON'T - it doesn't mean the flush didn't work! It just means you need more flushing :) Think of it like a kitchen sink that's clogged - sometimes it take more than one bottle of Liquid Plumber to get that big clog unstuck...and bingo, on the 4th bottle, it works. That does NOT mean that the first three bottles didn't do their job (or that they weren't necessary) - it just means it was a big clog.
