I tried it!
I took 15 mg, measured with a syringe off of a 10 mg scale...not the best method, but the mg scale is coming in the mail soon.
It did remind me of shrooms a lot. The come-up was amazingly fast and nausea free, the first psychedelic I've tried that didn't have a body load at all. My past psychedelic experience includes shrooms, 2c-i, 2c-e, 5-meo-dmt, salvia and DXM. My only bit of nausea was fleeting and cured by a loud and healthy belch.
Visuals were cool, a lot like shrooms, except I got noticeably more CEV and slightly less OEV. During the come-up, all the cars that would drive by in the distance would look exactly like toy cars. My sense of perspective was completely fucked. Me and my friends spent the first half an hour coming up just walking around dizzily feeling fucked up. Patterning was amazing, especially when I was on the ice. We walked on a ice rink next to a school but it felt like we were walking on a lake...cool shit.
Intensity of 15 mg seemed to be about a half-eighth of shrooms, but these things are hard to gauge based on the variability of tripping. One of my friends took 10 mg and was definitely tripping less than me, although he's usually very sensitive (at least to phenethylamines)
My trip wasn't amazing though; I didn't feel like I got much out of it. The whole time I felt like coming down, and I had terrible circular thinking. These things are more due to my set, but I couldn't help but be extremely paranoid about all my friends around me. Everything they said seem to carry extra meaning. Their words were a plot. When my friend talked about the sunset I could see the hidden motive in his words and would start to plan my words accordingly...it was all in my head.
I never found shrooms to be a very helpful psychedelic either, it's hard to process your thoughts when you keep forgetting everything every 3 seconds. I much preferred 2c-e. Endless hours of stimulated insanity coupled with realizations bubbling up from my inner consciousness seems to be more to my taste.
In terms of length, I was expecting a 4 hour trip. I took around 4 and at about 8:30 I considered myself mostly down, but still going just a little. Then I smoked three bowls and that completely changed. On other psychedelics, if I smoke weed after the come-down it just makes me really high and brings back a couple aspects of the trip, but this time, I was tripping, just as hard as my peak. It was almost as if the trip completely started over again. I still live with my parents and they are opposed to such experimenting, so coming home was difficult for me.
Sleep didn't come until 1 in the morning, even after the weed.
P.S. (to nife): I'm still a greenlighter (15 posts) and cannot send PM.
