If contractions start late in the night or very early morning and don't start at 5 mins - more like 15 - panadeine forte is fine - will take the edge off and hopefully let you get a few more hours sleep before the main event when you will need your conserved energy!

Sometimes hospitals policy is if you have had contractions for a day of so but not close but you are tired ... (specially if first time) and are only a couple of cms dilated they will send you home with temazepan and panadeine forte to help you get a couple of hours sleep as first labours can often be looooooong

hope that helps
