benadryl explained: AC (acetylcholine) gives you focus, memory, and clarity. Nicotine enhances acetylcholine. benadryl turns AC completely off. This makes you unfocused, have temporary dementia, and hear hyper realistic voices in ur head. AC filters your subconscious and what's actually real. benadryl turns that off, causing you to hear or see in the corner what you're subconsciously thinking about.
