There is a definite amphetamine-esque undertone to the "ecstatic" feeling of MDxx, but only in terms of the body high. A very particular facet of the drug gives justice to the "-amphetamine" suffix of it's chemical name, but it is quite obvious it's far different from any traditional amphetamine. You get tingles all throughout your body, yawning feels amazing and sends tingles down your spine. You feel excited, peaceful, open, but also in control. Due to pupil dilation, bright lights of any kind appear to be fascinating; a street illuminated by average everyday street-lights looks more glamorous than Vegas. The world appears as if some cosmic energy has covered all of existence with a thin layer of glitter.
During a roll, you feel only variations of one single emotion: LOVE. Ecstacy is chemically-induced love. It truly is happiness in a pill. You feel closer to everyone on a cosmic scale; you feel compelled to be completely honest with others. Even with regard to people you previously disliked greatly, you may not grow to "like" or "love" them, but you understand that you must respect them because they too are humans, therefore part of humanity, and therefore part of you.
You are content with being a human being, and feel comfortable about your hang-ups and insecurities. You begin to understand that it is not just your strengths, but also your weaknesses, that comprise your individuality; and you grown comfortable with your own shortcomings. You realize that problems are real, and must be resolved, but you must never let them bother you and you must NEVER pay them more mind than they deserve. You see the world through new eyes, and the new perspective you gain is refreshing, optimistic, and motivating.
You gain a new vibrant, optimistic practicality with regard to your own life, and feel a oneness with humanity, who you realize feels and experiences much of the same things that you do. You realize that life can suck, but it can't possibly be all bad, evidenced by the fact that it is even possible to feel as good as you do. As cliche as it sounds, you feel like a young child waking up on christmas morning; you are excited about living in the moment. I think, in a nutshell, Ecstacy is falling in love with life again.
I don't think that many would refute the fact that there is most certainly a reason this drug is called "ecstacy".
