What's the longest you've been in a plateau and how much weight did you loose after it was over?

Hi all. Firstly, I just want to say thanks to everyone that post questions, answers, progress pics and more here. I read them in my down time.

I am on a fast presently, it's been going well however at day 6 to now, day 11, I've stalled weight loss. It's literally been the same weight these past 5 days. I know it's normal and have read about the "whoosh effect" so no issue, irks me GREATLY though but I know it will pass..eventually.

So.. I was wondering, what are some of your experiences with long plateaus and how much weight fell off right after?
