Hacking for fun is one of those activities that engulf me and make me forget to eat for many hours.

Used to be fun-sized Kit Kats. Now it's 3 Musketeers minis.

I'm pretty sure by washing them down with diet Mt. Dew they have negative calories.

Black coffee with a touch of honey.

Raisins.

Bland but doesn't upset my stomach.

Coffee, black.

Or if it's after 5 PM or so, beer. But my code quality drops dramatically after a couple of those...

Club Mate and Cheez Crunchers

Lots of green tea, 1,5 - 2 litres per day. Not sure if thats healthy or not.

Same here, often jasmin blended with some Lapsang Souchong ("smoked tea") to give it a bit more punch. I've been doing this for decades and haven't noticed anything other than that it makes you pee quite a lot - a good thing as it serves as a natural screen/keyboard break.

As someone who also drinks litres of tea every day while at work, I have never tried blending two different types of tea.

Do you blend them 50/50 or have you found a better ratio? (I'd assume you don't need much lapsang)

A pinch of Lapsang is enough, I never actually measured the ratio. I do blend tea all the time, sometimes with Rooibos, sometimes with spices ('Yogi tea', cinnamon, cloves etc).
