I don't know what it is about skittles, but one box (480 mg of DXM) has always gotten me waaaaaay higher then the couple times I've tried 700 mg of pure DXM using agent lemon extraction, or any other drug I've had for that matter. Sometimes it even seems like theres a 5th plateau, even though I know theres no such thing. I love the coming up, I live the peaks, and I love the afterglow, which is like PCP without hallucinations. I've punched entirely through a door on this stuff, and broke the bowl on my pipe trying to stir it with a paper clip. I've never had any side effects aside from the usual cold sweat and super fast pulse, while pure dxm just makes me feel very wierd.
Note: Everyones Chemistry is different. The fact is I have a super liver and a high tollerance to pills. I took over a gram of acetominophen when I was 12 and had no side effects. Of my original group of friends that did skittles, only two of us are left. I do not recommend skittles to anybody, and I believe this drug surpasses most 'hardcore' prescription pills on all fronts (how high, how addictive, how dangerous, how life ruining). Honestly, 8 skittles won't hurt you. I told my friend the same thing so he took a whole box died in a puddle of his own damn vomit. My other friend that OD'd spent a day in ER. Don't do skittles.
And to my fellow metal heads I highly recommend the band Hunab Ku. Best trip music I've heard thus far.
