If we re hungry and our blood sugar has dropped, we will be more irritable. Cut down on the stimulants.
Caffeine is a known stimulant.
Too much caffeine can make us very irritable and edgy. For years my husband was addicted to a particular type of soda pop, loaded with caffeine. The high sugar content in the soda quickly made its way into his cells, giving him a burst of nervous energy. This, combined with the caffeine, made him agitated, irritable, and snappish unbearable to be around. In addition, the sugar in his one soda every hour routine left him uninterested in breakfast or lunch.
