How does selenium help with symptoms. I have Hashi's, and had most of my thyroid removed. The remaining bit promptly quit working. I am just looking for help with fatigue and muscle pain. I have split my Armour dose 2 gr am 2 gr pm and am taking 20 mg cortef (recently posted I took 40mg - brain cramp, couldn't add) I have problems with short term memory and "brain fuzz" like I'm detatched. Despite all this I feel sooo much better than when I was on synthroid. I also take Wellbutrin...and would like to get off it - I have seasonal affective disorder, any suggestions. I do appreciate the ones I have received and I have learned much from reading.
