Day 2 Master Cleanse: Blue Fingers?

So its my first time on the Master Cleanse, and I am on Day 2. Surprisingly, I feel pretty good.

I do have 2 concerns: I am absolutly freezing, and my fingers are turning blue. I feel like this may be caused by Detox, I normally smoke cigarettes, have a terrible caffeine habit, and drink too much alcohol (journalists dilema)

Has blue fingers happened to anyone else? Is it really just my body in detox shock? I plan on going for 10, and pushing it to 14 if I feel good.
