Harmaline is strongly psychoactive by itself, not necessarily a good thing though. My experience last night:
0:00 - 300mg harmaline FB dissolved in equimolar citric acid (aq)
0:30 - mildly intoxicated already, noticeable audio distortions, slowed thoughts, tinnitis, laggy field of vision.
0:33 - 70 mg DMT FB, accidentally added 3+ equivalents of citric but ¯\_(ツ)_/¯ down the hatch it goes. In hindsight, I think I was already experiencing confusion. Luckily, I weighed the DMT beforehand.
0:55 - nausea begins.
1:00 - vomiting begins.
2:00ish - still no effects from DMT, decide to give up and take pepto bismol, which immediately ends up in the barf bucket as well. Miraculously fell asleep.
5:00 - wake up, still nauseous, take pepto bismol for real, clean buckets and toilet, 20mg melatonin, brush teeth, fell asleep again. As far as I can tell, 100% of the DMT got puked out.
I experienced synesthesia several times - sounds became flashes of light or shifts in color uniformly across my visual field. At times it was quite aggressive. Besides that, the only "visual" effect was an inability to focus my eyes. After puking my guts out with my eyes closed, I opened my eyes to find they had become crossed. It took several seconds to realize what happened. At first, I thought stomach acid had somehow dissolved my eyeballs, which obviously scared the $h!# out of me.
Audio distortions were much more salient. Every breath sounded like a jet passing over at high altitude. Music became disharmonious and seemed to continue after pressing pause. I lost interest in music, which is good because I dropped my earbuds into the pool of vomit anyway.
The headspace does have its virtues. I noticed myself thinking about a variety of things from a different perspective, and coming to realizations I should have arrived at sooner. If only I could remember what they were...
The headspace does have a dark side. Putting together coherent thoughts was difficult, I became confused easily, and body discomfort was ever-present. I think harmaline is psychedelic, but also has some deliriant potential. Every time I puked it looked like some sort of creepy face formed in the vomit. Just pattern recognition, not a visual distortion, but somehow convincing nonetheless.
I'm gonna take some time to recuperate, get some water, sleep, and food in my system, and then come back to look for a better way of tripping. I currently have harmaline and methylene blue for MAOIs. I actually prefer the methylene blue LOL. Smurf diarrhea and urinary discomfort are nothing compared to what happened last night.
Some ideas I have floating around: grind up some pennies and convert my harmaline to THH, or just get some harmine. I might try sublingual harmaline at some point in the future, but I'm afraid to taste it too soon after puking. When I was a kid I couldn't stand the taste of tomato soup or tomato juice for years after puking some of it up.
