This stuff can be tricky... The highs you get at first will never be felt again and to buzz like that will need very high doses that will leave you feeling emotionally very shitty for days after.
Why not just smoke weed to relax as mentioned? Not as euphoric, but the sides are minimal. Even ghb would be a much better option.
Most the stuff is just precursors from China anyway, real MDMA is super rare. Unless you got some freaky good connections, it was not real mdma, no way.
My party days are not 100% over but using ecstasy or any form of it is. They even sell research chemicals that are said to be close in feeling but just missing that "oomph" the real shit gives. You can read about them at bluelight.org but I would stay the hell away.
Happy Rollin'
