I would say that sugar rush is pretty good now, especially considering it probably takes a move action to swallow the candy. you could probably simplify it by just saying, that, the candy produces an effect that acts exactly as, "Expeditious Retreat," does, except that you CAN move towards your opponent(s).
Umm... Expeditious Retreat has no restriction on what direction you can move. It just gives a 30ft enhancement bonus to your speed. The spell specifically says this to stop people from thinking it can only be used for retreat.
