I just took my first intentionally icy primal shower. Zowie! There's snow on the ground, but I just needed to do something to shake it up, so to speak. I had to turn the temp up some in the middle, so I could stand it long enough to wash my hair, but zapped it back to icy after that. I felt like my hair was freezing solid! I can see how it could get addictive though - my eyes are still popped wide open from exhilaration.
Also, I'm nearing the end of another 24-hour fast, then out to another horriday party. It's been increasingly stressful re: work and other challenges, and several disappointments across the board lately. Plus a cold or sinus infection, I don't know. But I've stuck very tightly to eating primal (including delicious grass-fed beef patties and avocado smoothies) and for the most part have maintained healthy sleep, most nights, despite everything.
