Doc Parsley’s Sleep Cocktail is designed to restore commonly deficient nutrients associated with sleep. If you routinely don’t get enough sleep, take this product every night. If you’re trying to catch up on sleep, take the supplement every night until you feel that you have caught up. Once these nutrients have been restored to optimal levels, most people experience improved sleep. Your body is still doing all the work. The product can also be used for jet lag. Please see Doc Parsleys website for more information.
