I have Aspergers Syndrome, and ADHD.
it appears you are having the same approach to MDMA as i did, I researched it thoroughly fir about a year before i decided to try it. because of my ADHD i'm prescribed Dexamphetamine which when i planned that i was going to try MDMA I stopped taking it 4 days before i tried MDMA for the first time as i knew it could interfere with the experience.
I advise that when you try it, you may need support from a good trusted friend who is experienced with the effects of MDMA to guide you through the coming up stage, When i tried it for the first time it was more overwhelming than what i expected it to be. I started to freak out a little, lucky for me a group of ravers who were there took care of me as i was at this rave by myself. and because of their guidance and help I didn't freak out. thats why i recommend you don't try it alone.
sure it can stimulate you quite a fair bit in the way of talking alot, and physical energy, but be prepared to have a massive brain buzz (like having voltage buzzing through your head) , your perception on reality and where it is may be changed as it did with me, but then again Everyone is different, although I have aspergers your experience may be massively different to what i had. so I strongly recommend that you do a bit more research about it on erowid, and here, and if it comes to a final decision to try this mind altering drug that will change your life in some way, make sure you have an experienced friend to help you through, If something feels strange whilst on the drug don't be afraid to say what your feeling, this was the main thing that got me through the peak.
I must admit tho, after I tried MDMA, I have noticed a big change in my perception of reality and the world around me, I can't fully describe whats changed but there is a permanent change that i can still feel to this day. so be prepared for the unexpected as well.
but overall i enjoyed it.
