52 , heavy eyes and sleepiness the next day AFTER gardening. Can anyone help or empathize w/me?

I also suffer from various food intollerances IE: yeast, fruit,alcohol. I'm going to have allergy testing again, but the most recent offender is now my garden. UGH! I feel fine just after the exposure, it's not until the next morning is when I feel the heaviness in my face and the irritability in my behavior, along with brain fog. Can anyone shed any light on this for me?Thank you!!
