I have been having a hard time with this one. I just listened to it again for maybe the third or forth time before writing this review. Throughout the whole thing I can feel the muscles in my face wanting to smile a little but its not the same as nitrous really. The tone at the very end is the best part and makes me feel really happy and grin quite large. The effect does last for a while though. This isn't my favorite, but it is quick and nice to put you in a giddy mood.
