Sigh. As I understand it every pregnancy is different. I don't believe anyone can give you 'hopeful' stories of binging and everything being ok....that is simply a way to hide in denial.
Get honest. With yourself. With your dr. With your husband, the father. One day at a time. Do the right thing, even when no one is looking. All the hiding and secrets will drive you insane....do it now.
One day at a time. All any of have is today. A day to take hold and do what is right.
