wait whoops didn't mean all of the info was incorrect. BUT if you eat shrooms on a completely empty stomach then your motabolism IS NOT working at it's peak and therefore the trip will take LONGER to hit if you have had even a small snack BEFORE ingesting the shrooms the trip WILL set in faster. and i have always heard of and experienced that good shrooms will upset your stomach and an empty stomach always hurts worse than one that had a snack. i always have something so my stomach is not empty.
now on to the orange juice. once again everything i have ever experienced and heard says that it is vitamin c that will increase a trip, i personally take a vitamin c supplement when i trip.
i took a glance at that link and i am medicated so i would never try any of this stuff and i only glanced maybe i missed something.
but bottom line i say have a snack before and take about 1000+ mgs of vitamin c and avoid any lactic acid(milk) for the best trip you can get.
