Another possible harmless remedy comes from the Yoga technique of Neti (sp?), it is a special pottery pot with a spout that you put warm saline water in, lean way over a bath and tilt your head just so, then you pour the warm salty water in one nostril and it comes out the other (TMI I know). I've used this technique for years when ever I get blocked up and it really helps. Maybe you can google it?
yes I have ssen this technique in a yoga book I have but there is NO WAY I could do it. Salty water makes me what to heave! Even the Fess is only just barable!

I will call the midwife tomorrow about it. Like I said earlier last time it became a full blown infection. The breath right things sound liek an idea too.
