The lack of sleep will not kill you although yet another night of sleeplessness can feel like death the next day. You do know the other symptoms and also that they will begin to clear in a few days. You may have a particular symptom that clings to you and seems to never let go. Lack of sleep is mine. For others it seems that anxiety is common I guess I am simply restating Opio. I am about 90 days out now and here I am typing at midnight instead of sleeping. My insomnia seems to be finally getting better and I slept 6 hours each of the last two nights. That ends up getting me so much energy for a change that, as mentioned, here I am. I am an experienced insomniac anyway and know that - as Opio stated - there is no use fighting it and if you keep a good attitude the lack of sleep really isn't too bad. I would look on it as a symptom of my changing my life. If I wasn't getting free of the crap I would be sleeping just long enough to wake up and start looking for some more all over again.
