For me at least I felt pretty wired and all high strung, was not a fun drug at all. Well that was on day two. Like the initial day doing it when I was out partying, drinking, smoking weed, with people it was alright because I think the other stuff kinda masks it. But the second day, both times, I was chilling at home and was just all agitated, couldn't sit still more than like 15 minutes, and just literally had a "I'm up, no way I'm sleeping" feeling for most of the time. Then I finally crashed out at like 5pm-ish day three and slept for around 18 hours lol. That stuff is so fucking stupid.
