Benadryl is something that should NOT be taken lightly. Just because it's easy to get and legal does not mean it's fun to get high off of. It can cause a worse trip than overdosing on LSD x10. Seriously, Benadryl is a deliriant and you'll most likely end up insane, in a psych ward or a hospital if you down a whole bottle. Your HPPD will be driving you up the wall, and it's mainly a horrible experience for 99% of the population. It's good for what it should do, act as a medicine against allergies and such. It also helps with sleep. But trying to avoid your body shutting down for the night and staying awake to trip.. ehhh. Stay safe kiddos.
