All of them depending on what day it is, what time, and type of gameplay. On a Saturday morning I will have coffee on patrol farming engrams, materials and strange coins. Some milk with breakfast while at the tower with cryptarch, followed by some orange juice before hitting Court of Oryx. For lunch some soda is nice when doing strikes. Iced tea is great for the afternoon while in a raid. After dinner maybe a few beers to loosen up for crucible. And finish it up with a glass of room temperature water while at tower dancing the night away.
