I drink two black coffees and perk right up!
But since you don't do coffee, an alternative is either 1) a loaded, nutritional smoothie or 2) an energy bar! I find granola & oatmeal really energize me quickly too. You can find tons of vegetarian/even vegan energy bars around.. they're very yummy & give a quick boost to wake up! =)
Also if you do eat some dairy (like me), Carnation Good Start really packs A LOT of energy quickly when added with milk of any kind (soy, rice, moo, any really). Its a powder packet and you just mix it in & drink! I'm getting away from processed stuff now, but this is always a fall back.
