To the person posting staying mdma is safe to use on SSRI's you need an upper cut mate. Do not take mdma whist on SSRI's I have seen enough people fuck the chemical balance of their brain, if you are taking medication for mood instability you should be leaving anything alone that interacts with your serotonin receptors. Safe answer would be leave all other drugs alone, fix the issue that got you onto SSRI's in the first place then have a good break (at least 6 months) before even considering taking something else, if at all ever. You tip the balance too much one way and if you are predisposed you may not come back.
