Chills

Just finished day 3 yesterday. Everything has been fine so far, no detox feelings.
Dug up my garden yesterday & went for a 3 mile walk. Lots of energy. The only strange thing that has happened so far was that yesterday, about 4pm. I got cold. I'm here in San Diego, so it was about 70*F. But I got cold & no matter how much clothing & blankets I put on, stayed cold until I went to bed. No fever, though, just couldn't get warm. Anyone else experience this?
