I reckon you can't beat putting a towel over your head while breathing in steam from a few drops of Eucalytus & Menthol in hot water - clears sinuses!
My hubby and I both have a lot of trouble with sinus (the joys of living in the country and working in the grain industry). My MIL bought us both Olbas inhalhers and they work a charm. (and they're only a few dollars from the health food store - basically they just have oils in it that you sniff).

Hope you feel better soon

Some useful herbs vitamins and their dosages:

Usual dosage:

Yes its no fun being sick as I am getting over another virus and it can cost you a fortune on medication.

Hi Faye, I can give my sympathy as I too have had this virus for close to 3 months now and it is not showing any signs of going away.

Have you tried Difflam Forte Anti Inflammatory throat spray? I use this as it is about the only one that works for me when I get strep throat. It costs around the $15 mark from most chemists .... make sure it is the dark green pack as the others are not as strong.

I ended up in the hospital on Sunday morning after a really bad night and my husband just would not take no for an answer. I have to admit that they were fantastic and I had many blood tests and 2 lots of chest X-Rays and now have to see and ENT specialist in a couple of weeks. Not looking forward to that I can tell you, but I know it is needed.

I don't know that I would go down the road of so many Vit. C tablets as I remember being told years ago that you can make problems for yourself by over dosing and sometimes too much Vit. C can give you the runs. That would be the last thing you would need on top of this virus in my opinion.

Good luck and I hope we are both feeling better soon.
