Hello theresej,
Thank you for explaining your situation so clearly, and in so much detail.
It is now apparent that you know what you are doing; I hope that my words of caution did not offend you. I am worried about less experienced people acting on advice, either given on these forums or from ignorant doctors, without first carefully checking the evidence.
If you have not already done so, I suggest that you visit the excellent web site of Rose. This is a direct link:
