Rolled alone a month ago. I was in my hotel room and was bound for the airport in 5 hours, so I figured I should take it as I wasn't too familiar with the airport security. Yes, yes, I know, kind of a lame excuse coz I just really wanted to do something and I had a cap with me (quite the potent version too, and no, I didn't test it coz testing kits aren't readily available locally). Anyway, my rolls usually just last for about 4 hours, so I figured I had an ample amount of time.
Took half with an energy drink, put on some music, killed the lights, wore my wayfarers, ate mints and sniffed some Vicks inhalers. After an hour I took the other half. My, my. After a while I was dancing to my favorite tunes, feeling the familiar effects I was longing for months: cold, clammy hands; itchy brain; loose, jelly-like joints; music overwhelming your entire body. All and all, it was amazing.
Now, I checked out after four hours, having a bit of manic energy. I feel it coming down. Was at the airport after an hour. While sitting, I close my eyes from time to time and get visuals (a usual effect during comedown when I take this blue pill). So depression kinda slowly crept in. And I was feeling like I really needed someone to hug. I wanted to just hug someone near me at the airport, but of course, I'll probably get slapped or punched or something if I did that. Lol. Then Tiesto's "In The Dark" randomly played on my iPod and I felt connected with the lyrics, which is weird considering it's a really sad vocal trance song and I don't usually like such sad songs.
Anyway, my point is, if you can handle the possible depression after (or if you'll be taking something to ease the comedown), go for it. I usually roll only at raves, so I'm kind of used to having lots of people and friends around. For me, most of my vices are social ones. Social-drinker. Social-smoker. Social...E-tard?

So I guess it'll depend on how you enjoy yours.
