I get those floaters every now and then too. Usually the left eye also and typically after heavy nights of drinking.

They come and go but I like so ideas in your post. I would add that turpentine is a great option for removing parasites. Just soak 3 white sugar cubes with it, chew it down and swallow. I used to do this once or twice a week and remember feeling good. I need to start doing it again.
