actually, I think benadryl is one of the few drugs that does not have serious harmful side effects. When I took WFA we were talking about epipens and allergic reactions. My instructor said you can take as many benadryl as you want, it wont kill you. And ive never heard of it causing hallucinations, thats pretty wacked.
Go to a doctor and find out what you are allergic to. The last thing you want is a surpise anaphylactic shock which will have you in a coffin in under and hour(but usually in around 5 minutes) without the proper treatment.
