Make sure there is not an underlying cause to the pollen problem .
My own journey through 30 yrs of awfull hayfever peaking at spring time was uncomfortable to say the least . The pollen was just a trigger for me ,i had had far too much exposure to insectacides in the sheep industry which probably did the damage and various toxins in the food chain kept me on the edge , some foods will put me on the floor . Red wine and cola will trigger asthma attacks . However since finding out by accident what was going on , doing a detox and modifying my diet my hayfever has completly gone for the last 5 yrs . So have a good hard look outside the square there maybe something in the past or present that is at least part off your grief .
good luck i know what its like
