Overnight london to dublin?

i was wondering if anyone knows anything about overnight rail sail london to dublin?? or even overnight flights?



i fly into london-stansted at 22:00 monday and miss the last flight out to dublin from there, but need to be in dublin early the next morning.



my first choice would have been to just take the first flight out tuesday morning with ryan air but unfortunately it leaves at 6:30 and arrives in Dublin at 7:45 which is too late for me.
