I'm in the same boat as you, assuming you have bipolar disorder. I take effexor, buspar, and lamictal. I'm looking for similar info as you. From what i've figured out so far, there isn't a dangerous reaction between the meds and the mdma, but there is with your disorder and the mdma. It will make the lithium stop working and could send you on a manic spiral. Unless you are on it for seizures, then i dont know. Isn't it strange how people with mental disorders start using drugs? Guess were all just a bunch of fucked up people.
