I didn't realize how much my medication helped even out my sleep, moods, and general outlook on life. Thyroid medicine makes a difference. Not taking it I am watching my sleep deteriorate, my concentration sucks, and I'm craving salt of all things. I envy a cow or a horse having a salt lick. I've devoured almost an entire bag of salty corn chips. I snapped at a student, tried to pick a fight, then laughed with my sister with that sound on the edge of hysteria. I sometimes wonder if doctors think through what these tests do to their patients. For one, I lost my patients. I wish I could just stay home and curl up in a ball for 5 more days. This had better work....just say'n.
