Thank goodness I only seem to get the sinusitis the once and a dose of antibiotics fix it. It makes you tired and the headaches are horrid, so you have all my sympathy. I'm dreading spring and all the flowers, I've started on my rhinocort already and the telfast and polaramine are ready to go. I sort of walk round like a drugged up zombie for a while until the poor old body gets used to the drugs and develops enough antihistamines of its own. Too make it worse I love flowers in the house.
