Two things to keep in mind with this material as I've now seen it happen to multiple people (and myself);
1. There will be a strong desire to re-dose in the first hour or two. Heed my warning and do not go through with it if you're new to this substance. Treat it as a one-shot type of deal since this trip has two phases (or peaks). Re-dosing seems to mess up the clean transition to the second phase and not add much to the overall experience.
Instead I find it best to wait until the next trip to explore a higher dose. Adding on say 3mg to a 7mg dose doesn't seem to add much, where as waiting until the next trip to attempt 10mg would make for a much more fulfilling trip.
2. There will be a strong desire to abort the trip for some people when they enter phase two. The "rolly" phase wearing off into an intense psychedelic state seems to cause distress in a lot of people. If you wait 10-15 minutes the anxiety will go away and you'll find yourself in a very content, sedating and trippy state. I've seen this shift catch a lot of "vets" and "hard heads" off guard.
Basically it's like coming up all over again for about 10-15 minutes, you just have to accept that and let it settle back down.
If you really think you need to abort with a benzo by all means, just know that you'll be robbing yourself of the best part of the trip since it's just getting started when that "phase shift" happens.
As such I approach this material differently than I would something like LSD, mushrooms, 2C-x, or any other similar substance. With 5-meo-mipt everything up until "phase two" is what I would consider the come-up. You could also think of it as having two peaks.
