I wake up in the middle of the night really anxious too. It's very annoying because even though I might only be unable to sleep for an hour or hour and a half I still have to get up for work the next day. It messes up my routine and makes it hard for me to get up in the morning. As if it's not hard enough already. If I take an anxiety tablet in the middle of the night I find it almost impossible to get up in the morning. A few times I have been more than just a bit late for work. Oops. Easier to take the tablet before I go to sleep, but then how do I know that I am going to have one of those anxiety nights? Pretty silly set up, I say. Hope you are having uninterrupted sleep soon.
