How to Increase Your Energy, 15th century

patient in bed looking dapper Getty MS Ludwig XV i, f. 13 (15th c.)

Also, place the eyes, the heart and the tongue of the nightingale under the pillow, or in the bed, and it shall keep him waking while he lies there, and whoever drinks it, he shall never sleep.

15th century medical compilation (British Library Sloane 3489, f. 1r-v)
