My daughter 37years old, mother of 6 yr old and 2 1/2 year old, almost finished student teaching / masters program, divorced, living with us: was just putting kids to bed and felt dizzy, light headed, hands shaking like when you are real hungry and blood sugar drops . She laid down for 15 minutes or so and felt a bit better. Could it be a drop in blood pressure ? Anything that should be immediately addressed? Obviously under great deal of stress and tired.
