Gatorade is fine: Water is cheaper.

Hydration, heat: Proper hydration gives you the best chance to have your veins full, ready for venipuncture. Drinking fluids which do not have caffeine helps, and applying heat to your arms for several minutes may help to dilate the veins. A bean bag placed in the microwave for several minutes will be warm enough for this.
