Can you tell me if there is a difference between diphenhydramine hydrochloride and diphenhydramine hci?

No difference: You're rather precocious if you're really 9yo! Anyway, HCl is shorthand/abbreviation for hydrogen chloride (hydrochloride) so diphenhydramine is diphenhydramine, a 1st generation antihistamine used to deal w/allergy symptoms, but also known to be sedating, so it's often added to other medications intended for sleep, eg Tylenol (acetaminophen) + diphenhydramine = Tylenol (acetaminophen) PM; Excedrin + diphenhydramine = ExcedrinPM
