Have you tried food grade diatomaceous earth? I just started on it yesterday...it is VERY cheap if you buy it in powder form...and VERY immediate! I took it internally - 2 teaspoons in a glass of water and I also put some on a q-tip in my nose...had spontaneous drainage, also twirled some in my ears as the stuff I took orally caused them to freak out I guess...but I saw for the first time, the moving fibers...tried to get video of the several dancing fibers, but my camera couldn't quite catch it...
