shedding question;

On Friday, I noticed that my snake's color was very dull and almost grey--needless to say I was horrified until I realized that she was preparing to shed. Anyway, her eyes were blue and cloudy on Friday and Saturday and I noticed yesterday everything had cleared up but her color still wasn't very vibrant. I noticed several creases in the skin around her neck and her skin seems to be very loose and wrinkly. The humidity's about %72 [too high?] and the temps are fine. She's got a large bowl of water too. She's remained in her warm hide for the last three days. The last time she appeared was on Thursday when I fed her. How long does it take for shedding to began after the eyes clear?
This is my very first snake, therefore, my first time witnessing the shedding process.

Shedding usually takes between 7-14 days for mine, you will love how they look when they are done shedding (at least i do :P)

It's very funny and like clockwork! my sweety takes exactly 9 days everytime.

Mine took about 12 days when she shed. We kept the humidity at a constant 80% and she shed fine, so IMO 72 isnt too high for a shed.
