Hugs. I'm going through something similar. Last night I went to bed at 10.30 and I was still wide awake at 1. Then up at 3 for a while. Again at 5.30 and now 7.30 and I'm up getting ready for work. By lunch time I will want a nap at work (and of course not get one)

My bad sleeping stemmed from having to wake 2 hourly to check on my DD but it got better over time. Now it's up ***** creek again!
I can't take anything to help and have also seen the dr with no recommendations.

The thing for me is it every night and when weekends or days without DD come I just spend them napping! (not a good habit but I'm so exhausted)

I used to take an over the counter drug called restavit (doctors advice) every so often and it would give me a decent sleep but I would wake up feeling like I had a hang over.

The one thing the gp told me was go to bed when I was tired, phone/tv/books etc no where near bed (I wake up and start playing games on the phone) and ignore the clock.

I hope you get some answers from the bb ladies (and I'm definitely going to be watching too!)
