The pits when you can't sleep or when finally do keep waking up...and yup the exhaustion is just another thing to add to an already overloaded body. So in a long winded way, yes I experience that....what I do about it...I am in the very early stages of a new medication...thus far, it has in the very least helped me get some rest....even if it's just four hours;

Please keep us posted on your progress.....
