When you manage to not fall asleep after taking a large amount of Benadryl (a “recreational” dose). You will feel very heavy, as if you weighed like 3 tons. Walking will be near impossible and you’ll look like a crazed drunk to anyone who sees you. Realistic hallucinations (not enjoyable by any means), paranoia, and nonexistent conversations with people who aren’t really there is all very common as well.
