Hi Rachiex,
I did try one night ... to see (if and) how long I could sleep in them for.
I must have laid in bed, on my back, for about 30 mins (or maybe 45 mins, at most?)
But I just couldn't get comfortable! I had to keep fighting the urge to roll over onto my side. And that in itself was frustrating. (Goodness - I don't know how the Brava girls do it!!!)
And *just* as I was beginning to snooze ... one dome decided to go "pfffft" and popped off!
Sheesh, I thought. All that effort, for nothing!!
I realised that I might just as well have had a good noogle before I went to bed, and then jumped in with happy, fluffy boozies. And enjoyed dozing off more or less instantly, with the blissful freedom to stretch, roll, curl up, and generally indulge in that wonderful embrace that is sleep.
So that was my experience.
But I know one person here on the Noogle forum reported no problem sleeping in them (they used Brava domes, I think).
So it might work with an NB - who knows?
All you can do is give it a go. (And maybe I should have persevered - just like with noogling!)
Best of luck
Mojo
