Hi Cookie,
I had the same thing for months before I started taking meds. Felt like I had drank about 20 cups of coffee. I was off balance, spacey, couldn't concentrate, really shaky and tense...like I had a constant surge of adrenaline running through my body. I wished I could just have one panic attack and have it over with...but that feeling lasted for weeks. Once I started on Paxil it went away. I believe it was constant anxiety on top of the panic, it was annoying because no matter how relaxed I was, I always felt on edge. I would tell your doctor about it.
