Sleeping well attempting to sleep anyway.

Anyone elses head go into overdrive at night time like you have a vortex or something swirling around inside your head. Takes me ages to get to sleep usually I'm up all night painting and have to tier myself out mentally untill the sun comes up so can sleep finally. Like I'll be awake for a full 24 hours longest I've gone without sleep is 40 hours that's usually when you start to halosenate so try and avoid that but if I'm excited I can't switch off like wise if I'm anxious. At the moment I'm kind of anxious and excited as I have a metal gig coming up which I'm forcing myself to go at alone to try and help better my anxiety and my tattoo coming up I guess which I'm nervous yet exited for.
