As we started the hike I took MDA and in about 20 minutes I took a half a blotter of LSD - I started feeling that I took about 120mg of MDA, not 60. Then I remembered about Fabomotizole and it's potential MAO-A inhibitory action! I was prepared for a full blown serotonin syndrome effects - there was a LOT of sweating, a lot of temperature fluctuations, extreme confusion, tracers and colors abound, I could not walk and told my friend to call an ambulance if it gets worse. Luckily it settled after about 40 minutes and I became very euphoric and full of empathy and even took the remaining LSD.
Lesson learned and be warned - Fabomotizole definitely has something to do with serotonin
