The first time I took it, I was at a show, and I took like 100mg I think? I had a big hangover the next day but I also drank a lot. I enjoyed the high quite a bit, I do remember not feeling very social and having a massive body high. After that I took it probably 6 times over the course of months, as fake MDMA (if indeed it was that but I really think so). I enjoyed the high usually those times too, but the aftereffects make it not worth it, I get the hangover with or without alcohol. My best time with it was when I took a small amount, like 40mg, it was more subtle and didn't wreck me afterwards (but I still felt some hangover). There just aren't enough positives for the negatives. it also tends to give me a headache towards the end of the night (it happened the first time too, when I knew I was taking 4-FEA).
