Ditto what Ginevive said: stop stressing the poor little thing out by making it live in light 24 hours a day! If the eyes of the snake are just now turning cloudy, you could be in for a shed anywhere from 2 to 7 or so days from now, most likely around 4 days. Now is the time to bump up the humidity and stop using lightbulbs in his visible spectrum 24 hours a day. I bought a 75-watt blacklight bulb at WalMart for like $6 for nighttime gecko viewing and it definitely creates a warm spot, so if you insist on not providing belly heat to to the little guy, that should be one option you could consider.
