Just to clarify re: malabsorption, just a possible theory that could be part of the puzzle -- if it does hold true for you, hard to know if it's the chicken or the egg! And it could be a separate issue entirely but I do believe with MS, so many things can be intertwined. I hope you get to the bottom of this, April! We can't have you waste away to nothing and I'm concerned! There's got to be SOME reason this is going on!
