Well this weekend I tried a little test, I got rid of all the air freshers, washed all my clothes & bedding in fragrance free soap, no fabric softener. Did not wear perfume, didn't clean with chemicals. Bathed in fragrance free soap and shampoo and was feeling better, headaches were way less. Went to Lowes because DH needed some wood and got a awful headache after just 5 minutes in the lumber department.
