Waking too early. Any ideas?

I fall asleep quite quickly but every night for the past 6 or so weeks I have been waking around 4.00am and I cant go back to sleep. Ive tried to read to get me back to sleep, Ive got up and done stuff but I am really too knackered to do either as my body feels weak from lack of sleep and all I want to do is go back to sleep. Ive been on antidepressants for about the same length of time but my GP doesnt reckon it is that. Any ideas would be much appreciated as I am finding I have hardly any energy to do anything in the day which isnt helped by the fact that I am recovering from an long term illness that have left me quite weak anyway.
Thanks all.

I go to bed at about 11.00 or 12.00.

I am sorry to hear this- I too suffer from the same problem- I have found that audio books help me to drop off again- nothing too exciting obviously- you can pick them up cheaply on e bay-
