This happens to some people with Benadryl as well (though doubt its related, just anecdotal). Curious - have you tried multiple (reduced) doses?

Benadryl is a first generation antihistamine which crosses Blood-brain barrier and makes you sleepy. Its mechanism of action is very different from melatonin and it has much more severe side effects (bad feeling after wake up) than melatonin.
