I must admit that when I read about this, I was sceptical... a couple of lights to shove up your nose that can cure hayfever?! However, having tried everything else under the sun to try to decrease my havfever symptoms (including herbal medicines that did nothing, and over-the-counter-medicines that just made me feel like falling asleep), I thought I'd give it a go.
The first thing to say is that when you have this switched on, you look hilarious! It makes your whole nose glow red, which I hadn't realised (I wondered why my father-in-law started singing "Rudolph the Red Nosed Reindeer" the first time I used it!), so it's probably best to use it somewhere where you won't feel self-conscious. But... it works for me!
Within a minute of finishing a treatment, my blocked nose starts to clear (sometimes one nostril more than the other, but usually both). I do then have to keep blowing my nose for a couple of minutes until it totally clears, but that's no different to what most hayfever sufferers have to do anyway! Thereafter, I get several hours of either little or no hayfever symptoms. As far as I am concerned, it is fantastic!
Since I bought this (a couple of weeks ago), I have typically only used it once to twice a day, as this has brought my symptoms well under control, and made any remaining symptoms easily bearable. I am now going to start using it three times a day as recommended to see if I can elminate my symptoms entirely.
Obviously this might not work for everybody, but if your hayfever symptoms make you feel as lousy as mine did, it's got to be worth a try, and won't cost you more than a couple of nights out.
