I am interested in the answer to this question as well, how long after tramadol should you wait to dose lsd? I have a strong hit of good clean LSD thats been waiting on me for a couple of weeks in a dark place, and I have gotten a bottle of tramadol today so that further puts off how long I must wait to dose(I was waiting for a good time to trip anyways) but now that I am going to be taking this tramadol for at least a week at least 400 mg + a day how long afterwards should I wait to dose the acid? also just for reference, I had take tramadol for a week before I got these 2 hits, and took one of them, less than 24 hours after my last tramadol dose, I had stupidly forgot all about the tramadol and the possible interaction, I was just excited about the acid, so I gobbled it down, then realized what I had done and spend half the night researching "serotonin syndrome" while I was tripping lol
