I had dry eyes (although not as dry as yours) for a few weeks. It was the first time ever, and it made sleeping, in particular, pretty uncomfortable. So I put castor oil in them just before sleeping and I slept great! The oil stays in there a lot longer than eye drops. I have contacts, so I couldn't use the oil during the day, but if you don't have contacts you could try it day and night. I read of the idea here at curezone. I also read about people using olive oil and coconut oil. So you might want to try that while you're waiting on the herbs.
