I am a nursing student and a CNA. My position is a casual/supplemental position on a telemetry unit and I've been working there for about a year. I am fortunately in the financial situation where I do not have to work often, and I will work a shift or 2 every week or every other week to maintain my supplemental status. I work because I love being a CNA and think that it is valuable experience to a nursing student. The only thing is, is that I can NEVER sleep the night before I work. I never have problems sleeping or falling asleep unless I am going in to work the next day. I have no doubt that this is anxiety related, as I have anxiety that I am being treated for. I always make sure that I exercise and avoid caffeine the day before so that I can try to fall asleep and stay asleep but sure enough, I'm wide awake at 330 waiting for the alarm clock to go off. I don't know if it's that I'm worried that I'll sleep through the alarm clock or what, but I can't ever fall asleep and it's driving me crazy. Does anybody have any advice or encouragement?
