Well, I finally tried 5-MeO-DMT. Today I measured ~7-8 mg of my HCl salt, the powder was clumpy so I had to crush it into finer particles.
T+0:00: The insuflation was only slightly painful, and my heart rate got immediately increased.
T+0:01: I walk around the room few times, feeling slight tension in my body.
T+0:03: I decide to lie down on the bed, the tension makes lying a bit uncomfortable. I turn on my player and start listening to music.
T+0:12: The comeup is slower and less intense than I expected, but I probably reached +2 on the Shulgin scale. No real visuals: slight trails and increase in static, pretty much like other 5-MeO-T's
~T+0:20: I reached plateau. Music sounds more detailed and unusual mental effects becomes more pronounced. I was anxious before experience and hoped that it won't be amplified by this psychedelic. However, 5-MeO-DMT pushed me into completely comfortable and very calm state of mind, which remained for the whole experience.
I didn't really keep track of time for the next 40 minutes. I lie on my bed, stare at the floor and wall , listen to music and try to think about my life and who I am. The effect of 5-MeO-DMT on ego was pronounced: ego is suppressed and distorted pretty much. OEVs are noticebable. At ~T+0:40 my girlfriend lies on the bed near me(she is sober and she have been browsing internet during past hour), we were kissing and fondling each other. Sorry, I am not Alexander neither Ann Shulgin to describe this part of the trip, but sex on 5-MeO-DMT was very magical and awesome.
One really interesting: it was soooo difficult to say something to my girlfriend, I mean, there was sort of inner barrier that was hard to get over.
T+0:55: My gf's roommate knocked on the door and I had to put my pants and jeans on very quickly. The effects began to disapper.
T+1:00: I look at the clock. Wow, 1 hour passed and I still not close to baseline, although I am coming down.
T+1:03: I go to the bathroom, feeling that it was one of the most magical trips I ever had(but i must admit I didn't have much trips yet

)
T+1:20: Slight movement in the visual field is present and staring at the tunnel-like picture is very fun

The drug is still definitely in my system, and this is not afterglow.
T+2:00: Mostly baseline. Afterglow effects were felt for the next 1.5-2 hours.
tl;dr: +2.5 5-MeO-DMT experience.
