An unexpected, incredibly large bowel movement that makes you feel as though you are lighter and increases your overall energy level.

Most day changers happen when you're already having a pretty good day. You might feel perfectly normal. Then you get the rumble. Nothing big just a little "hey when you get a chance" message from your belly region. Then you sit down and proceed give birth to a food baby you didn't even know was inside you. You walk out of the bathroom proud, accomplished, and feeling light on your feet. Your good day was just changed to a great day. Nothing can hold you back today.

Also you may feel hungry.
Person 1: walking around like king of the world almost glowing

Person 2: what's got you in such a good mood.

Person 1: just took a day changer. Nothing can stop me now!
