Increased my Armour dosage to 60mg. I felt way better for the last three weeks or so. The heat today outside is very bad. This all started for me two years ago on an seriously hot day just like this. While driving to work I almost couldn't make it there. Really shaky, severe disorientation, instant irritability and nervousness. Blurred vision, breathing normal just heart rate high. Thought I was going to pass out driving. Anyone else have this reaction to heat? Am I going to pass out? I could explain all this to my endo and he will just stare at me. I trust you all more.
