When my housemate gives up trying to convince me of the virtues of raspberry beer, I'll revert to augmenting Tea* with
Malibu.
The beer's not bad, I just prefer to drink things that're better than "not bad"
But, engaging in inebriation in order to "be a better gamer" strikes me as kind of irresponsible
*That's strong tea, brewed for at least 15 minutes at the boil, with milk.
