How much alcohol does it take to get drunk?

I am 5’10, 150 pounds. I’ve never been drunk before. (I’m 16) The most alcohol I’ve had in one sitting is 3 mike’s hard lemonades, and a pina colada that didn’t have that much alcohol in it. I am planning to get drunk with some of my friends who have been before. I plan to drink on a fairly full stomach, in not a very long period of time. This is a awkward question but I would like to know so I don’t accidently over-do it and pass out or something. By the way I will probabaly be mixing 40% vodka with juice, ice, and fruit to make drink smoothies (with my magic bullet :P)
