Beth, don't you DARE give up!! And if conflicting advice is confusing you, then just go back to what Heather says, rather than our interpretation of what Heather says, or what works for us. Everybody is slightly different but Heather's approach helps everybody. So keep it simple and stay focused, hon. Your body will tell you what it needs, but only if you pay attention to what it's trying to tell you. Okay?
Hang in there and keep it simple! (oooh, I'm going to make that my new signature)
