I would suggest to anyone wanting to try DOM, start LOW!! I've had one experience with it, and I consider it to be my one bad trip. It started off great, pretty euphoric and EXTREMELY visual. I was actually having problems balancing because the visuals were so disorienting. Don't really know how to explain the bad trip. It started off great, i felt very serene and I found everything hilarious. I was cracking up the whole time. However, i couldnt stop laughing which made me short of breath. During the come up my friend was telling a story of a video he saw where some soldiers took acid and as he said "Were dying in the streets laughing". I remembered him saying that, and during the peak I took it very literally. I suddenly knew that i wasnt gonna be able to stop laughing and that I was going to die because of it. There ended up being about an hour where I was intensely crying and screaming, asking my friends to call my brother, sister and father so that I could say goodbye before dying. There were some disturbing visual manifestations of the mindset that i wont go into. I only got through it because my friend who dosed with me held me hand throughout the orderal and kept repeating "You're safe. You're going to be fine. We took the same dose. Look at me, I'm fine, I'm safe. We took the same dose, you're going to be okay". It was a literal dying experience. I experienced death, and it was horrifying, but as soon as it passed the trip started to wind down and I started to feel better.
I say that that was my one bad trip. However, 90% of the trip was very enjoyable. That 10% was absolute hell. It was traumatic and I wouldnt wish it upon anyone. I can tell from that experience that DOM truly is a special chemical, and I will try it again. My friend and I split a 5mg tab and he took the slightly larger half, so my dose was 2.5mg at most (assuming we didnt get a blotter with a hotspot). The main trip lasted at least 12 hours. The peak was probably a good 6 hours. I was still experiencing visuals at the 30 hour mark. And that was only 2.5mg. I can not imagine how some people can take 7.5mg. I am going to try the chemical again some day, but I probably wont be going over 2mg.
