Dr, Alpert. This subject is a big question for me. I have hypothyroidism, am on levoxyl, but still feel crappy. I found some great ifo on line(http://thyroid.miningco.com/health/thyroid/library/weekly/aa09897.htm) This page in particular has a great list of symptoms for thyroid, which are identical for MS, and fibro, all of which I have, along with bi-polar. Actually I feel the antidepressant I am taking has been of great benefit to me. I have so many questions about all of these symptoms because as I stated in a previous post, I am having great dificulty cognitively, and I truly feel in my heart that a lot of it is not the MS like all of the doctors think. I believe it is a number ot issues contributing to the problem. I will be anxious to hear your take on all of this. Thank you for listening. Help is needed desperately. Donnamaye
