it took 3 days for me. My best advice is to go to bed. Cover your eyes, and rest. Keep hydrated, and be patient. Take this time to listen to music, or a book on tape, or prayers, or nap time. I found keeping my eyes open was more than I could take.

You will find if you keep ONE eye open and one closed, it should be much much better. If you must be up, then patch one eye, and later in the day, cover the other.

I hope you feel better.
