How much LSD should I take?

I have for years been fascinated and mentally preparing myself for the LSD experience and am finally doing in in an apple orchard (I heard being outside in nature is really cool). Now I have never done a drug in my life, besides smoke pot (only a tiny bit) with my cousin a few years ago. I am only doing this once in my life just to try it and want to know how much I should take to have a crazy, holy ****, everything around me is so colorful and I'm somewhere out of this world experience. I want it to be just a full out, balls to the wall, moment. I presume a high dosage but I don't know how high. I am 17, 5' 7", and am about 135-140lbs. Please help me.
