My insomnia is considerably worse than normal right now. I may be at the illness where equilibrant starts working, but probably not. Of note is a particularly high resting heart rate in bed - generally between 75 and 90 bpm averaging around 80. Two and a half years ago, I was a high performing athlete and my resting heart rate at night could be in the 40's or 50's. I consume no caffeine. I'm assuming the relatively high resting heart rate is either the cause or associated with something that is making my insomnia worse. I guess I should suggest to my endocrinologist doing a 24-hour cortisol test. I will see cardiology in about two weeks and they have scheduled a metabolic stress test.
