What risingfire said. With thyroid energy, I feel like I have all the time in the world, like I did when I was a child—it’s as if time moves slower when my thyroid is functioning optimally—and I feel an excitement to do things, but it’s accompanied by this sense of calm or peace, while adrenaline energy feels like there isn’t enough time in the day to get everything I want done, like time is flying by, and there’s usually this background feeling of anxiety, a fear of my own mortality, really. With both energy sources, I have moments of euphoria, which made distinguishing between the two and adjusting my diet and thyroid dose accordingly quite challenging in the beginning so going by my temps (including temps of extremities—cold feet, hands, nose and/or ears are a telltale sign that adrenaline is compensating for thyroid and cutting off circulation to them to keep the core and vital organs warm), pulse rate and slightly more involved but very helpful is evaporation rate, i.e., average total fluids consumed and eliminated via sweat vs urine in a 24 hr period.
