I took allergy shots for 3 1/2 years. I believe some of my medical problems, especially my high blood sugar, were caused by them. After all that time, my severe allergy to grass went from a 5++, on a scale of 1 to 5, down to a 5+. Nothing else changed. So, I stopped them.
I do take local raw honey and it has helped, but it takes several weeks before I noticed any change. I don't like the flavor of honey, so this is a bit of a chore.
