Yep...I've been through the same thing...probably around 34 weeks too...just couldn't get to sleep...it's got better but I'm still struggling a bit...I was just saying to my DH that "sleep isn't the lovely companion it used to be"...

I've found that having a shower before I go to bed has helped. I don't normally like to have a shower before bed...but it has definitely helped...

I've also not a nap person...but have been trying to have a 10 minute nap when I can...that helps to get through the day.

Hope it improves for you...
