Don't over-do it too much, The more you eat might seem like a good idea at the time because you will (obviously be tripping harder and seeing more visuals) but it gets much easier to have a bad trip.

One time I ate 4.5 grams of whole caps, and powdered stems inside capsules and the trip got pretty rough, I got it under control with some relaxation techniques. but that turbulance in my trip kinda messed up the rest of the day.

So make sure you have a stable mind through out the day and think of ALL the possibilities of your actions.
