I really been sick since March we believe was allergies to something outdoors but couldn;t pin point it. My friend thought maybe I was allergic to fabric I just started to use It took me to about 3 weeks ago.I started on Clariton. I know when I go to Walmart where the potpourri is I can't stay in that dept. very long because I start sneezing. I hope you figure out your problem and doesn't take as long as with me.
