Welcome, Tom. First off, I haven't heard of that order of treatment either, but it is a sure bet someone in this group has. Secondly, there IS no protocol. Just about everyone here is either going through it, has gone through it, or is taking care of someone who is going through it. So anything you ask, say, or answer is just fine, as long as you are not peddling quack cures (grin). You are going to have many more questions as you proceed through your treatment, and the best place to get answers is from someone who has been there before you. Come back often.
