Query: If you haven't seen an RE yet, maybe could be useful...

This book just doesn't give any details, if you have already seen a RE even for a short first visit you know all of this stuff. The only thing it might be good for is if your husband has a really short attention span for this type of stuff, this might be helpful for him to read (it only takes about 30 minutes)and it could help him understand a bit of what is going on in your head. But really you could tell him in less time then it would take to read the book. I'm just not really sure what the author's thought they were adding?? Amazing that these types of no info books get printed. Not a helpful book, save your money and go talk to your Dr's and the nurses that's what your paying for.
