caution is a word that i can't understand

so after a few months of terrible sleep patterns/not being able to sleep at all, i fell asleep at 7:30am, and woke up at 10am.
the natural sleeping aids (teas and organic pills) are not working, so i decided to go to a doctor. she prescribed me sedatives for the night, and stimulants for the morning. also, she prescribed some pills that will up my levels of seritonin.

fun stuff!
