Methadone. What exactly is it? I have done it on 20 different occasions and still doesn't understand it. I know it's a synthetic opioid with a qualitative action similar to that of morphine. I know it has a lengthy half-life. But I don't know what to expect from it. I still don't, even after trying it repeatedly. In fact, each time I've tried it has left me more confused. Let me explain. Sometimes, it's a wonderfully blissful feeling. I remember taking 20mg's and writing "this is devine, truly a feeling of utter contentment" in my journal. I also remember taking 20mg's and complaining the whole night of restlessness, rage, itchiness and the complete and total lack of euphoric tranquility. One time, I took 15mg's and rode in my friends car, only to be delt motion sickness like I've never had before. 15mg's was so intense, I puked and poured sweat and moaned and made my friend turn the car around. Another time, 40mg's did nothing but make my head itch and put me in a NASTY, vengeful, angry mood. WHAT IS UP WITH METHADONE?! DOES ANYONE KNOW WHAT IM TALKING ABOUT?!
