At home: 50% decaf (either packaged, such as Starbux Half-Decaf Breakfast Blend, or I mix half and half myself. Water, Crystal Light lemon, or Ocean Spray Diet Cranberry-Pomegranate juice (sweetened with Splenda).

Restaurant: Decaf or iced tea, and water.

On the plane: since AA uses horrendous tasting instant decaf mix, I pass on coffee and stick to water.
