OMG I am still rocking back and forth as well..lol I actually enjoy it, it sort of is like a sleep aid. Perhaps it's my weird way of mentally tricking myself that we are still on the ship enjoying the amazing energy 
Gawd I sure miss being on the Westerdam with all you wonderful people!! I have Olivia Cruise seperation anxiety..LOL
I hope for those that are being bothered by the rocking, it goes away soon. If it is making you sick to your tummy, that can't be fun :(
Blessings to you all!
