Sometimes I use a herbal calming remedy, valerian, available OTC.

It just calms, it doesn't make you sleepy or interfere with working or driving.

Either it really does work, or the placebo effect works!

Some people also take up running/jogging for the reasons you have mentioned, so they don't have to take out irritation on people at home (even if they haven't done what you told them to do).

I usually commute by bicycle. It is a great way to energize going in to the job, and a great way to blow off steam after a trying day.
