I have tried many remedies over the years, including all the usual sprays, both prescription and non- prescription. Rhynil is non- prescription, which tells you something..... It's completely harmless. In fact I bet you could pour the whole bottle up your nostril in one go, without any ill effects. That's how harmless it is.
It's not particularly cheap, though. If you used it all the time it would cost you over 170 pounds per year. But it does appear to do something. Although it didn't stop my snoring it did in fact, gently clear my sinuses and REDUCE snoring. I'd rather use this that some of the more aggressive nasal sprays which can be bought over the counter from normal chemists.
There is also one big advantage to buying this via Amazon, as opposed to buying it direct from the British Snoring and Sleep Apnoea foundation.... Amazon don't bombard you with spam emails, which was my experience when I previously bought anti- snoring products direct.
Give it a try..... if you are a snorer you'll try anything -and this product will , I assure you, do you no harm whatsoever.
