Only did E once with a few good friends back in college. We stood by this creek smoking doobies and just shooting the shit for hours and hours. Watched the sun come up, went inside and smoked ourselves to sleep. Good times.
Only did acid once too... I had an up and down time. Laughing my azz off one minute while watching the walls melt, nearly losing my mind the next. Overall not a fun time.
Booze, cigs and weed always did me right so that's what I stuck with for the most part.
