I am a 71 yr female. For a couple of months I have had headaches, nausea, dizziness, weak and extreme sweating. I can't even sweep my floors without feeling as though I will pass out and have to sit. Just the thought of food makes me sick. I have been to my GP and he just took labs for my thyroid to make such my dosage is correct for hyprothyroid and colestro. Then he went no further. Said everything was find. But it is not fine when I can not function without getting sick. Do you have any suggestions.
