As always, depends on setting. If I'm sitting and resting, that feels great. If I'm dancing, that feels great.
Usually as I'm coming up, I start pacing just to get a feel for the amazingness, and then fairly soon I calm down and get really relaxed and just chill with my friends and talk. I'd say the stimulation is similar to the stimulation from the classic psychedelics. Shrooms will keep me adventuring on no food and no rest all day, and I can't sleep, but they don't cause the restlessness or pacing or rapid talking of traditional uppers. Same with MDMA. I can lay on the floor and stare in someone's eyes and just contemplate things for hours. In fact, even with all that love I can start feeling too lazy to give a massage, or stand up to go get something for someone. But the moment I do stand up, it turns out I do have the energy. Like psychedelics, MDMA is just a nonselective amplifier of a lot of things, just in more positive-shifted way than traditional psychedelics.
