So here it goes again...either I can't fall asleep despite taking my sleep meds or I wake every two hours and feel like a zombie the next day. This has been going on for 2 weeks and I am so exhausted I can hardly breath. Is there any way of knowing if this is a high cortisol or low cortisol problem as I know both can cause issues with sleep. I get into bed exhausted and it feels like my heart is pounding..out of my chest, like adrenaline is flowing widely through my body..then I sweat. I want to buy seriphos but don't want to take if it's low cortisol. I can't go on much longer like this as I am pretty much unfunctional the next day. I feel like I am in a fog and can't think...help!
