Drinks

This should be mostly water honestly. Avoid soda.

Two cups of coffee max.

A few cups of tea.

Alcohol:
If you're strapped for cash this should not be bought. Keep servings at or under two a day (4 oz of wine is a unit, or 1 oz hard liquor, or one 12 oz beer). Drinking a lot costs money and will pack on the pounds and affect your health if you're not careful.

Box wines keep for much longer, don't need to be kept cool, and are cheaper per unit of alcohol. They can also be used in cooking.
