False labour pains giving me grief.. please help?

I have been having 'false labour' or braxton hicks for the last week - apart from the disappointment of the labours not giving me my long awaited baby, I have the added difficulties of not being able to rest up properly making me concerned that I won't be up for the real labour when it finally arrives. The 'false labours' start EVERY time I sit or lie down and stop when I'm up and moving around. The pain is enough to keep me awake every night (contractions come and go every 5 minutes) - last night I only managed 1 HOUR of sleep! Help... I can't continue like this much longer - what do I do?
