For Allergic Rhinitis "Benadryl really helps take the sinus pressure away, and I found out recently it even worked best for my migraine. Out of Tylenol and Motrin, Benadryl was the only one to knock it out. It does cause me dry mouth and drowsiness. It also helps to calm me when I feel a panic attack or anxiety coming on. I'd rather take Benadryl than psych meds or all kinds of prescription meds any day. I hope it stays working wonders for me because Claritin and Flonase did nothing for me, and I don't want to have to try anything else."

For Allergic Reactions "I was given Benadryl at the hospital for an allergic reaction. It instantly shot my heart rate up to 217 bpm, and instantly my mouth got dry. I couldn't swallow, my chest felt hot, like an elephant was sitting on it, and I got really cold. It put me into shock, my body wouldn't stop shaking, I could breathe. It was so scary, I thought I was dead. Thanks to the doctor's quick response, he saved me, but it almost killed me."

For Nausea/Vomiting "I took a single pill of Benadryl, and it made me vomit, nauseous, diarrhea, dry throat, and gave me a stuffy nose. I wouldn't give this to my worst enemy."
