i used those pregnancy pillows and it was great. it gave some real comfort. i had those U shaped ones, that took up most of the bed. DH was away for most of my pg, unfortunately and i did get to hog the whole bed.

i also found 'sleepy time tea' just before bed did help me relax and also brauer's sleep and insomnia relief.. but check w your chemist to see if you are ok to take it. my naturopath recommended them.
