Ratdancer, I am sorry to hear your husband is currently doing poorly.
I don't know what role the Copaxone may be playing in your husband's symptoms.
not the only issue to fix, one thing does stand out to me:
People with ms are known to have a number of nutrient deficiencies. These usually show up as low in the "Normal" range for each lab test. What is needed for improvement is to get the levels to be in the high end of the "Normal" range (or higher). One of them is zinc. An insufficient zinc level is know to cause reduced taste, smell and appetite. A low zinc level can also cause an altered sense of taste.
The first step
to dealing with a zinc issue is to get 2 simple lab tests from the doctor (serum zinc and copper). With these, we will have a better idea of your husband's levels of these nutrients.
The second step
is to get a good supplement that contains both zinc and copper ( because zinc and copper affect of each other). Here is the one I take and like: http://www.vitaminshoppe.com/p/solaray- ... vnMnvldXuM
I'm sure others will be chiming in with more help. Dealing with your husband's depression is another area where things can get better and this one is very important.Having a lot of problems/challenges means there are a lot of ways for things to get better,
