My first labour started at 9pm too... what is with that??? Couldn't sleep for the rest of the night... ended up having a long chaotic labour (contractions weren't spaced... my labour was basically one long contraction especially after they tried to speed things up by putting my on a syncotin drip )

My other two labours were induced in the morning after a reasonable night's sleep. Slightly more managable. Still... avoiding syncotin/oxytocin would be the best way to go if you can... it's evil stuff. My doula at least helped me insist that i be given the minimum dose during my third labour... it still worked but it meant that my contractions were spaced like they were meant to be.
