Tea! Any tea.

OK, well I guess if water isn't allowed at all then I'll have to go with the Dehydrated Water canister from Space Quest 1

Boob sweat

Unsweetened soda, like Bubly and that French one I can't spell.

Edit: Or coconut water.

Liquid Dihydrogen Monoxide with a few crystaline samples of more Dihydrogen Monoxide

Tea. If I need to choose a type, Green Tea.

Where my Yerba Mate homies at?

Coconut water!!!!!!

My favourite drink after water (which is genuinely my favourite drink) is coffee. I don't think, however, that I would like to only drink coffee, so I suppose I will have to choose tea. Especially if I can have any variant

If I have to choose specifically then I'll say decaf Yorkshire tea.

Pedialite. I know some prefer Liquid IV, but I like that I can get Pedialite anywhere and it’s relatively cheap. I give it to my kids instead of juice. They also have popsicles which is great on those super hot days.

Duvel, Belgium's premium beer. Duvel translates to Devil, the beer most preferred by Joe Cocker and the reason he wouldn't return to Belgium because it would be the end of him. Looking back he had a point. (1944-2014)

Coffee. Coffee is my life blood.

Apple juice with a good amount of milk.

Carbonated water. Leave it open for a while.

If we're allowing categories, I'd probably go for smoothies. There's enough variety in them that I wouldn't get bored and it's got a good amount of water in it so I won't die.

Whole milk

Tea

Beer.

I'd say Coke Zero, but technically this is just a "water with some chemicals in it" goof, and therefore not allowed.

Piss.

Birch sap is my first thought, but I might get tired of the sweet. Some kind of tea then, maybe rooibos. It's sweet or savoury as the occasion demands.

Chloroform.

Can you drink glycerine?
