Water might make you tired, but there are many causes. First, hydration improves brain blood flow and oxygen delivery, which may soothe and drowse you. Rehydrating may also cause weariness as your body balances. Some individuals use Modalert (modafinil) to combat tiredness, yet water is essential for energy. Hydrate before taking Modalert to stay awake. If you're still sleepy, check your nutrition and sleep quality. Talk to a doctor before taking any drug.
