This is me as well. My anxiety and stress has been SO high for SO long that I think my nervous system is permanently stuck in 'fight or flight' mode; not even the Klonopin I've been on for over a year has ever really given me any relief. I wake up every day feeing jittery, shaky, oftentime sweating and very nauseous, and just this strange "out of it" fogginess in my head. It can take hours to lessen, though some days are worse than others as to how much it will lessen. Although I've had anxiety since I was a kid/pre-teen, waking up feeling all those sensations started pretty abruptly for me around 2014 - at first I thought maybe it was a blood sugar thing but medical tests showed it isn't. It's awful to live this way. I also wake up like every hour or so, and have lots of anxiety dreams. I wish I could escape this miserable life at least for 8 or 9 hours a night but my body won't even let me have that much...
