I have been wondering how restless nights affect your temps. It seems to me that when I have had a bad night my temp goes really low, but for some reason this always happens around O time as well, so I never can tell. According to FF they recommend taking your temp anyway and recording in the notes and special circumstances. I have started to do this and my charts are beging to form a pretty good pattern regardless of the odd bad night/s.

All the best with charting.
