The times I've taken mdma on its own, one dose of about 150mg - 180mg and just sat at home with MrsMist, put some music on and chatted for hours, it's been beautiful.
Go to sleep at a sensible hour like 12 am or 1am, ive woke up feeling absolutely brand new, so has she.
The harsh comedown comes from mixing other drugs, particularly alcohol, dancing like a loon, getting dehydrated and not sleeping. Suprisingly, you feel like shit for it.. :D
MDMA when used sensibly and in the setting I mentioned earlier is magical. It seldom ever happens as I like getting fucked up and dancing like a loon all night, so the brutal comedown is my fault, not the drug.
