I have seen some postings about phase 1.5 and I am curious about it. Is this like a transition to phase two?? I am in day 4 of phase one and up until today have been okay, but for some reason I am sooo tired and cranky. My doctor told me it was okay to go to phase 2 to begin with, but now that I am in day 4 of phase 1, I don't want to just quit but I don't feel that hot either. Will this pass???
