I have been going thru a bad spell of anxiety. I got out of bed on Tuesday about 2pm. I have not slept since. Yes, I do suffer from insomnia but I have never been this bad. I am about to finally crash, thank god. I just do not understand why this is happening. I have sleeping pills, muscle relaxers, sedatives (xanax) but have chosen not to take them unless I have too. Is this a problem as we age. I know the insomnia is but has anyone else gone without sleep for over 48 hours?
