I have tried tracking my mood in excel and on paper as well as the number of orgasims I have and the cause of these as well as karezza. I generally find I have much increased emotional stability if I can limit orgasims with my wife to once or twice a week.
Lately I am using the app 'my mood', only used it 2 days so far, so definitely early days. Any recommendations on mood tracking apps? What is your favourite?
