Oh no don't worry it's not a problem. I either get sleep on the sofa straight away or if I feel like staying up I catch it up in the afternoon. I personally think that it's caused by these damn O2 tubes...well who wouldn't wake up if you've got two bits of plastic stuck up your noseI hate your sleep problems, @charlie1465.
The early dawn light is fantastic too.....but thank you sweetie. Sending hugs
