I have had various allergies all my life (none life-threatening), when I was a child I had a lot of food allergies that have since gone away, and I have always been allergic to cats, dust, mold, and pollen, most of which required very occasional antihistamines to manage symptoms. But just within the past two years or so I have started developing more serious food and inhalant allergies that continue to get worse.
It seemed to start with serious reactions to various types of beer and wine.
