Is it a panic attack?
For the last couple of weeks I have been waking up 2 or 3 times a night just soaked in sweat. It only takes a couple of minutes to cool down and then I half to change clothes and sheets so I don't freeze. I thought at first it might just be the increased dosage of prozac and abilify the doc gave me, but after reading some about anxiety I wonder if maybe I'm having panic attacks in my sleep.
I've had similar experiences that end up being medicine-related. I'm on Effexor and if I take 2 I sweat like no one's business! When you wake up are you out of breath or breathing fast? That may tell you if it's chemical or anxiety related. Most of the time, if I have a panic attack, I wake up before instead of after. I've heard of some people waking up during, however. Do you remember any of your dreams? Maybe you're dreaming about panicking.
