If your friend is drinking this daily, as with any medicine you build up a tolerance. So as he/she does this,they need more everytime.This should be addressed with a doctor.

Benadryl is an antihistamine, which can cause extreme dizziness and sleepiness. As with any suspected overdose, you must immediately seek emergency treatment.

You can't technically overdose on Beadryl. It's an allergy drug, and a weak one at that. At worst he's going to feel sleepy or groggy the next day.
