Shower steamers are designed to slowly release intoxicating and/or aromatherapy oils during your shower.  Place a steamer at the bottom of your shower.  For a longer lasting steamer, place indirectly from the mainstream of water. As the steamer gets wet, it will slowly begin to fizz releasing the wonderful oils into the steam of your shower.  Now all you have to do is inhale, relax and pamper yourself! (Can last up to 2 showers, depending on how wet they get.)
