Is it possible to be addicted to OTC sleeping pills?

To the point that one is unable to fall asleep without them?

I've been vaguely aware over the years that my husband takes sleeping pills, but I'd never really noticed if he took them every night, or how many he took. I thought that he, like many people, just uses themm once in awhile if needed.

Tablets affecting sleep?

I take an allergie tablet before bed to help me breath and prevent allergies, it also causes drowsiness's, im 14 would having something help me fall asleep be bad for my growth or anything because im not actually falling asleep naturally.
