Nothing like a good dissociative to really twist up a person's reality. Just check out the numerous iterations of the MXE and 3-MeO-PCP threads.
I'm actually originally from the 3154, but I didn't time travel because of ketamine, I time traveled because that's how you take vacations in the future. Had to make sure to travel to before I or any of my direct ancestors were born though... you definitely don't want to break reality. WHATEVER YOU DO, avoid your self in this time. We're all counting on you not to create a paradox.
Wait, there's no current version of yourself, just you? What does it mean?? 8(
But yeah, I think overall I prefer this time, although interstellar travel is pretty damn awesome... the best thing about this time is that we don't all live underground yet and there are still trees.
