Chocolate milk is awesome. I love that stuff, but vanilla milk I haven't tried yet just because I haven't found it. Please do tell more, got a picture of it or something by any chance?
I don't like neither tea nor coffee. I drink water or chocolate/vanilla milk the morning, and I can still be awake for a whole day with sth like 5-6h of sleep time
Also, for me it's no competition since I don't drink coffee, so tea all the way. Be it black tea with milk, green tea with lemon and honey, fruit ones or mint, anything goes. Vanilla and wild cherry were pretty interesting tastes.
