Cyclobenzaphrine (Flexeril) and MDMA?

[Liv4141]

I was prescribed Flexeril for muscle pain. I took 10mg once Tuesday night and am planning on rolling Friday night. I've been trying to look up how long Flexeril stays in your system and have been finding on average four days. I don't know if this would be true only after taking it once though. Has anyone ever taken a muscle relaxent and rolled a few days later? I'm obviously not planning on taken them together, but am worried if its still in my system something like serotonin syndrome could happen. Thanks!
