In brief: Perhaps

Psychologically, but not physically.
100mg is a high dose, do not climb any higher, and you should likely speak to a dr for an alternative with less side effects.

In brief: Can get habituated

I don't recommend someone your age to take chronic otc meds to initiate or maintain sleep.
Other causes have to be ruled out. I would start with sleep hygiene. http://www.sleepfoundation.org/article/ask-the-expert/sleep-hygiene.
