Suggest Treatment For Sleep Disorder

I've had trouble sleeping for 3 months now, waking up 3 or 4 times in the night and at about 4 or 5 am. I've been to the doctor, tried some sleeping pills for a few nights (they made me too groggy until 10:30am and I had to be up at 7am for work, so stopped). They referred me for CBT but I've heard nothing yet and got my own therapist now privately, for various things, not just the the sleep. After three sessions she thinks I'm doing pretty well, but has given me techniques to relax. I've been to a hypnotherapist twice, the 2nd time worked for two nights, and have tried MP3 downloads, none of which worked. I've just started a new job and have spent hours feeling almost painfully tired in the face of trying to work and living for the weekend so I can sleep and not have to get up before I've had enough sleep. Today I couldn't quite manage it before crying, and wailing with it. I haven't cried properly for a long time, but needed to weeks ago when I had some upset with a friend and even then couldn't let it out, so I was so tired that I cried properly. I'm sure it'll help, but I just don't know what more I can do. I can try more exercise and relaxation, and turning the pc/tv off earlier, but I can hardly make it through a week at work at the moment which I can't afford. I have an appointment with my GP, but to be honest, I get little real understanding or help from my doctors (whichever one is in today, anyway) when everything comes down to anxiety that I've dealt with on and off for years. Is there anything I've missed? I tried staying up until 2am to be too tired to wake up, but I still woke up, still felt exhausted, and didn't have a week or two clear to let it work any better. Going to be at 10pm is better than 11pm or midnight, but the constant waking up is ruining any real benefit.
