1. If you are eating (even very small amounts) the throughout the hour then you are obligated to recite an After-Blessing over the food. Depending on what you have eaten, if you have finished eating and do not make an After-Blessing within half-an-hour (if you did not eat bread or any Mezonot), forty-five minutes (if you ate Mezonont), or seventy-two minutes (if you ate bread) – then you can no longer make an After-Blessing.
