2C-I is pretty okay as long as you keep an appropriate dose and you don't snort it. It's a terrific trip though, I wouldn't hesitate to do it again, personally.

As for the effects, consider it like a readymade candyflip.

Its pretty surprising that you can get DMT too, I would think that because your dealer has 2C-I also he might be getting both that and 5meO-DMT from the same place. But it's not impossible that it's real DMT, and if it is, you're one lucky skunk.
