Benadryl + alcohol timing question

If someone took 3 Benadryl around 7 a.m. (likely 25 mg each), how long should they wait before drinking alcohol?

Person is 5’7”, 170 lbs.

Would 8–9 p.m. the same night be considered safe, or is it better to wait until the next day?

Just trying to be safe and avoid any bad interactions. Thanks!
