That's very normal lol. Especially on MDMA... I can get like that on other drugs too, but I usually have the sense still to know its not the best idea to send those texts, emails, etc but with MDMA, it just feels sooooooo right... til the next day... then its awkward haha. I've gotten better at 'controling' myself now, but when I do MDMA now, I'm usually with friends and try to stay away from internet, my phone, etc. If you must send a confession or a 5 page love letter, try to stick to friends who also do MDMA and understand haha. The thing is too, is that even though its sometimes awkward, sometimes opening yourself up like that is a GOOD thing and can be very healing... you just gotta be careful who you open up to about such personal things. Even though it feels like you can trust anybody when you're on M, you can't. A few years ago when I rolled on some incredible green transformers (one of the best nights of my life aahh), I wanted so badly to go talk to my mom and tell her all this stuff but thaaaank goodness I didn't. I realized that even though it felt so right for me, for my mom, who doesn't understand MDMA, it would have been really uncomfortable for her daughter to approach her, really high on drugs. She wasn't operating on the same 'level' of consciousness I was and she wouldn't have understood. So, I would just keep in mind how that other person might feel about it. And... only send messages to people who you can at least be honest with that you're high... otherwise people are going to probably think you're unbalanced haha.
"I always write out a nice status for facebook, or a long text to someone I like. Luckily I always get to the end, re-read it and then just think to myself "i'll read it again in a couple of hours and decide if I want to send it". ~ That is such great advice. I try to remember that I don't need to send my text, fb message, etc right that second. Sometimes just writing it out is enough of a release and you can decide whether to send it or not later on.
But yeah, you're definitely perfectly normal. I've sent some awkward e-tarded emails in my day. Now I try to focus on the people Im with, and if I really feel the need to write or text someone, I try not to do it while I'm peaking and really high, unless its one of my close friends who also roll and know how it is haha.
