Don't continually deny yourself sleep or use caffeinated drinks to constantly cover up your sleep deprivation. Continual sleep deprivation is not only bad for your overall health but it increases your pain symptoms (as if they aren't already bad enough) and affects your moods. I know that I am more cranky when I am tired.
Take care of yourself, you only have one life to live. Dealing with chronic pain isn't easy but it is important that you know that you aren't alone on this journey. If you are feeling alone, please find me on Twitter or leave me a blog comment, I will do my best to help connect you to an online support group or help you find additional resources in your area.
