I have an idea for the exhaustion in the evening hours. If the developers could make the energy drink last say...oh for 4 hrs. and make it readily available in the GROCERY section so you could buy as many as you need, then you could use it for the exhaustion hours so that most of us night owls could play. It wouldn't effect the way the game runs for those of you that are happy with it as it is. You could use the energy drinks, or not, depending on when you choose to play.
