I've never had a swollen lip from an allergic reaction until the past year. My body must've become more sensitive and released histamines from certain beverages I drank. It's only when my lips are chapped/dry that I get this reaction from drinking coffee or beer. Poor quality coffee and beer triggers the swelling immediately.
I've discovered that using lip balm helps decrease the chance of swollen lips because I only get this symptom during the winter months when my lips are dried out. Also, I've limit my consumption to only 1 cup of coffee or 1 beer. Any more than that, I run the risk of getting swollen lips. When I do get a swollen lip, I use a cold pack wrapped in a towel and hold it against my lips for 15min. I look like Daffy Duck when I have a swollen lip so I try not to drink coffee at work. I don't drink beer at social events either.View Thread
