Speed experience

[Eclipz]

Alright, I turned off the lights, made it a bit dark, lied down and took my headset and started Speed.

Really really interesting, At like 30% I had some weird reactions, I almost fell asleep, but I couldn't, when my body wanted to just sleep, It felt like I was getting a shock, full of energy.
Then at 65% I really felt happy, wanted to just run around, when I was at 100%, I were walking (well, running) to my PC, and damn, never typed that fast..really, amazing.

So how are your experiences with Speed?
