Ohhh I remember the rolling over thing too. DH falls asleep so easy that I didn't feel bad about waking him up and saying 'I need to roll' and he'd help me :P Could you ask for some assistance?
Oh and as for the sleep, people used to say to me too, 'you think it's bad now, wait til you have the baby'. Well, rubbish. Sure, you wake up a few times a night, but it's deep sleep when you sleep, and you can sleep on your tummy and your back (you can even sleep on your tummy if your boobs are full to bursting, you just gotta prop yourself right with pillows - it's bliss for a tummy sleeper).
So take heart, you're not too far away!
