Oatmeal may help if you are feeling irritable & cranky. The carbs in oatmeal trigger the release of serotonin that boosts mood & help you sleep better.

Recent studies have shown that after consumption of high carbohydrate food, the hormone insulin is secreted, which lowers the blood levels of most amino acids, with the exception of tryptophan, which is a precursor to serotonin, a neurotransmitter. When there are high blood levels of tryptophan in relation to other amino acids, it enters the brain at a higher rate, thus synthesizing more serotonin. While all carbs will give you this kick, stick to whole-grains (complex carbs) as they are digested more slowly and will thus keep you feeling fuller for a longer period of time. Examples of whole grains include brown rice, daliya and oatmeal.
