This symptom is one of the worse i have. Since i became sick, two and a half years ago, i am not able to relax, and it causes me insomnia. One doctor that i saw, a neurooftamologist told i was in permanent fight or flight state and my dilated pupils were for too high adrenaline. He told me i should take antidepressants (which i did until several days ago). It helped me to some degree, but still i feel i cannot reach the total relaxation state in any situation. Any thoughts? Any treatment for that? I wish i could do yoga, but at the moment i can't. I don't know how to do meditation.
