Have fun, just remember that when things start to get out of control, its sometimes good to try to remind yourself of what is real.
Oh and you'll know when you are about to "arrive" by the sharp stomach cramps*... the worse they are the harder the trip.
One of my favorite things about traveling to the mushroom kingdom, is that the harder you try to explain something, the harder it becomes to explain. Its fun you should try it.
*pains only last for a few minutes, tough it out, hold it down.
