I did that a lot in college. That and lots of Ramen (mmmmmm, Ramen).

Re: caffeine--I drink about 3-5 cans of diet soda and/or cups of tea a day. More often than not, it's caffeinated. 

Hmmm...after seeing some of these responses, my caffeine intake does seem rather high. Perhaps I need to find a healthier means of stimulation... 

Roasted chicken legs with potatoes. My sister is cooking, so it will probably suck. I intend to take advantage of my lack of coffee this morning and sneak in an extra cup during the day sometime.
I shall snack on something suitable (possibly suggary) if said lunch does not meet my demands. 

For me, it was a chunk of pork slapped between two floury baps, with a bit of mustard. 

fresh Summer squash, sliced into thin round wafers, bread it with flour, salt and pepper; place them flat in a pan. Slice an onion and place the rings over the squash. Take a stick of butter and cut up into several pieces and distribute evenly on top. Bake until crisp. Absolutely awesome.

Peanut Butter Cookies, take whatever recipe you may have for peanut butter cookies and substitute plain vanilla cake mix for the flour. You will need to at the very least half the sugar content of the normal recipe. 

I drink 32oz of coffee when I wake up, and usually have about 32oz of Coca Cola before the day is done. 

on average 2 bottles of diet coke/pepsi a day.
but no tea or coffee. 

Mission to score additional cup of coffee succeeded; No casualties. Sub-objective of chocolate snack: failure, but managed to maintain a peanut-butter/strawberry-stuff snack bar.

Dinner: Unknown. Possibly pork-chops, perhaps if no identified target then Burger King or pizza. 

Before work-snack:
Potato w/ bacon bits left over Campbell's soup. Still good when microwaved. Tuna-sammich to go with, make for a good combo. Mom will probably force me to eat some sort of vegetable. Anger grows. 

Now I'm exceptionally tired whenever I'm away from it. 

Seems to have different effects on me. SOmetimes I'm hyper, sometimes it mellows me out. Other times it makes me really really sleepy. But, it always makes me happy. 

Some smartass slipped extra chilli into an already hot pasta I was creating, way back when I was living away from home.

HooAAAARGH!! 

has one of two effects on me; first, it is an elixer that brings me back from the land of the dead in the morning. Any other time of the day, it is just mildly stimulating. I usually drink two to three cups a day. 

.. is only an really efficient stimulant... for my bladder only !!! 

and one variaty of Thai peppers -- a cute, bright orange thing that resembles a bell pepper folded in itself is sublimely hot and richly tasty at the same time. 

was a veritable FEAST of a submarine sandwhich with layers of turkey, ham , salami , green peppers, pickles, jalapenos, lettuce, and mustard, I even added a bit of parmesan cheese ontop.

delicious 

BreakFast: Standard bacon n' eggs breakfast. Eggs kinda cold. Mom made me take a vitamin pill the size of scampie's abs. :( 

1 cup of milk,
1 tub of Crystal Lite Classic Orange
4 cups of Vanilla Ice Cream

Mix in a blender and dump in a glass and drink. Cream Sickle memories from your childhood will come pourin' from your eyes like an avalanche coming down a mountain.

1 jar of candied cherries
1 jar icecream topper pecans with syrup
Put into a blender and blend into a paste
Add 1 cup of milk
4 cups of Vanilla Ice Cream
1/2 a bottle of Guinness Stout (about 8 oz.)
Blend, shake and drink.
This will cleanse your soul of all that has trespassed it. 

that's what I need to have soon, is a good milkshake. I like to add maple syrup as a sweetener sometimes 

A bad idea is to put a little watermelon flavored vodka into your coffee. It doesn't help taste-wise. 

is a bad idea under any circumstances. 

watermelon flavoured milk! 

Chilli-flavour vodka pwnx0rs.

Pear drop, liquorice and parma violet flavours are also pretty nice. 

has this odd taste of rot quality about it, at least to my palette. So, even the thought of watermelon flavored milk or vodka makes me queesy. Sorry. 

What about watermelon-flavored-chocolate-covered-horse-rectums-with-ants-crawling-over-it-dipped-in-honey-and-roasted-over-a-slowly-burning-carcass?

I saw that on Fear Factor once.
