This might be late considering your posting date, but when a snake sheds, first it's eyes will cloud. This is from a harmonal secretion that seperates the old skin from the newly developing skin. (known as being blue) After seperation is complete the secretion subsides or clears up. It may sometimes take about a week or more from the time a snake turns "blue", clears, and actually sheds. It's not uncommon for a snake to refuse to eat and seem lethargic while in shed either. In other words, everything seems normal to me
