I知 getting a lot of trembling inside me just now, feels like I知 about to have a fit!

Its usually at night, I知 ready to fall asleep then I wake up in a panic. I have pins and needles in my arms and some weird sensations in my head like I知 losing it. I feel all shaky inside mainly down my arms in to my hands, but also in my head.

Doctor put me on Propranolol for a few weeks but this hasn稚 seemed to work.

Has/does anyone else feel like this, its hard to describe.

I should also note its mainly at night but I'm at work just now and I'm getting it.
