Welcome to ThisIsMS, KB. With your extensive experience with the medical profession, you will have much to offer us, I'm sure. But we are willing to share our opinions and experiences when you ask.
Your reaction ("drifting between anger and desperate sadness") to your husband's diagnosis is completely human and to be expected. I think that because you and your husband have "already been through so much together" the two of you WILL handle this situation, too.
Your approach to the suggestion of Copaxone is commendable – research (even info here in the forums) and make the best decision for you. There are many people here, including me, who have opted to use diet and exercise instead of or after trying the approved MS medications. I have found the story of Dr. Terry Wahls and her dramatic improvement inspiring (http://www.TerryWahls.com
); although her diet is extreme, in my opinion, it holds some basic, usable ideas. AND it offers us the hope that things can improve.
We are glad you found us.
My hypothesis: excess insulin (hyperinsulinemia) plays a major role in MS, as developed in my initial post: http://www.thisisms.com/forum/general-discussion-f1/topic1878.html "Insulin – Could This Be the Key?"
