I usually juice 2 to 4 lemons and stick the juice in a bottle

and take it to work with me, along with a small bottle of maple syrup and cayenne tablets. Then, whenever I want some, I go to the kitchen, pour the maple and lemon in the appropriate quantity, stick some hot water in there and pop a cayenne capsule down my throat as I drink. Be sure to drink a ton of water when you take the cayenne or you'll feel a nasty burning inside as the capsule dissolves in one lump!
