I also live in the DFW area and allergy season has really kicked off. Irriation of sinuses helps to wash out allergens that are creating the misery. You will be amazed how much junk will release and come out after nasal irrigation. Helps to reduce swelling too. I use combination salt and baking soda water for irrigation, 1/2 teaspoon each in 1 cup boiled water, strain thru coffee filter, fill clean nasal spray bottles, let cool, hang head off bed lying on back and squirt few times into nostrils, massage under eyes, rest a little bit then say kkkkkk while getting up to prevent solution from running down the throat. In a few minutes stuff will start releasing. Make fresh solution every week since it does not contain preservatives.

Besides irrigating I also use Beconase nasal spray during allergy season.
