Ah, the dreaded Neti Pot. It just about killed me (that's an exaggeration, but...).
My wife has terrible seasonal allergies - so bad that I suffer with her suffering; her sneezing all day and night, snotty rags everywhere, etc.
A couple of years ago she came upon an herbal formulation that works like magic. Really, it works - like magic. Breath Easy RespirActin http://www.respiractin.com/art_naturalasthmarelief.asp
. It can be ordered from that website in Canada, or the US. In Vancouver, it can be purchased from Sweet Cherubim (Commercial Dr.), and probably at Finlandia Pharmacy (Broadway and Arbutus?), and probably at Capers, or Choices market (numerous locations on the West Side).
The chemical anti-histamines are not only vaso-constrictive, they cause a kind of dementia in the long term.
I don't have allergies, and have no commercial affiliation with the product, nor it's distributors, but I am confident in recommending it, as it has not only given my wife relief from her allergies, but given me relief from her allergies too.
Retails for about $49 for a litre bottle, and that should last you for the whole season.
