Coffee. Just coffee. And that's actually a somewhat recent addition, the regularity of it. I love breakfast foods more than anything else, but I've always felt sick if I eat in the morning, and if I do, I'm starving by noon. coffee alone makes everything normalized and I feel less of a desire to eat garbage foods throughout the day.
You, mk and I are in the same boat, we prefer not to eat breakfast and find it actually makes us hungrier by lunchtime if we do. These days, due to peer pressure, I usually have a small greek yogurt in the morning. Otherwise, an energy drink (judge away!).
Actually, no, but funny story. I grew up in the East Bay of SF. E-40 lived in the nearby super-rich gated community. Around the time I was in my freshman and sophomore year of high school, he was really big on the 'hyphy' movement. It was just, like, a subculture of hip-hop around the Bay Area. Anyway, he created an energy drink by the same name, and every so often when school got out, he had these crazy, tricked out ice cream truck-van-hybridized car things roll around with massive speakers on the sides blasting and would hand out the drink free. I don't know if he ever handed them out himself, but the kids went fucking apeshit for getting some. It was kind of a cool thing to see.
I tend to have coffee with cream and sugar (I know, I know..) and many days I'll have a guru energy drink, but I only rarely will have any kind of food. Liquids only in the AM.
