No one is arguing with you. In fact, those are some of the nicest replies I've ever seen from Zorbs (
). You asked for advice, you have gotten it. Just because you don't agree with it do not mean anyone is arguing. Zorbs can survive on little sleep and look amazing. That is one experience and opinion. Neither of you is wrong or right.
Take the advice you want, ignore the advice you don't and you will be fine.
