This has happened to me. It actually was what was the beginning of my downfall one month ago. I woke up, with exact same thing. I was eventually told it was allergies, that got so bad I got double ear and sinus infections but the anxiety was bad and then it all spiraled out of control since then.
Anyways, these symptoms can also be just from anxiety, but yes, the allergies can definitely do this. I was told to start taking an allergy pill when I got done with my antibiotics, but they make me out of it, and I'm still playing the "which medicine is right for my brain" game so I'm just trying to deal with the allergies for now.
I am going to take my first dose of Effexor tonight. The Buspar the last two days has some very weird side effects. Sigh....if it's not one thing it's another. I want to feel good again
