If you are suffering from allergies for 6+ months a year that is horrible.
My grandfather was a beekeeper, he swore by honey. You might want to give that a try. It should be as local to you as possible. None of my family are sufferers from allergies and I attribute it to the local honey we ingest.
A toasted peanut butter and honey sandwich is so good, even if it doesn’t help you it’s a tasty lunch.
I have not actually “suffered” from allergies for over 45 years. I just get a stuffy nose, take a gram of Vitamin C and my nose opens up. If I don’t take the C I might progress to runny nose and sneezing, but always keep a small bottle of C in my purse and a small bottle of water to swallow it with.
