Fun Fact: benadryl is a 1st attempt at an anti allergies drug and goes past the “blood brain barrier” which is why it makes you groggy and sleepy, but there’s a 2nd attempt drug (Allegra) that doesn’t pass the blood brain barrier which DOESNT make you sleepy
idk why that’s so interesting to me, ig I never considered that different drugs are attempts to solve a problem instead of just the solution
