When I answered before I gave my answer for live games, and forgot all about when I play online. My favorite drinks playing at home are coffee milk, made with milk and Autocrat Syrup, and V8 Spicy Hot juice that i usually drink plain but sometimes with a little rum in it.
It's great that you've found a drink that helps you stay focused during poker tournaments! Coffee can indeed be a good choice to keep you alert and clear-headed. It's interesting to hear that you switched from alcohol to coffee, as many people find that alcohol can impair their decision-making abilities. If you're looking to switch things up or if coffee isn't your thing, you might want to consider trying some mocktails. https://goodmocktail.com offers a variety of mocktail recipes that are refreshing and alcohol-free, perfect for keeping your mind sharp during those long poker sessions.
