Distribution of responses to the morning questions A “How rested do you feel?”, and B “How well did you sleep last night?” posed the mornings after Saturday March 7 (pre-DST transition) and after Saturday March 14 (post-DST transition). The bars show the number of participants whose response fell into each category.
