2 doctors agree
In brief: OTC medications
Unisom is basically a sedating antihistamine marketed over the counter for sleep just like tylenol (acetaminophen) pm. These can have lasting hangover effects and should be used per fda recommendations listed on the box.
They do cause tolerance to build so as per bottle, nightly use is not recommended.
