Eating pre workout is good. Be sure you are getting a good balance of fat/protein and carbs. 25% fat / 25% protein and 50% carbs (based on calories) seems to be good 'average' for keeping me feeling 'sustained'. The trick to not having the food cravings post night time work out is to eat those well balanced meals during the day.
For post workout, focus on hydration first. Drink lots and lots of water. When you think you've had enough, drink another glass. I find post work out hunger becomes managable if I'm well hydrated. Its worth the extra nightime trips to the bathroom.
In short, 3 'well balanced' meals, plenty of fiber and good hydration will help keep cravings at bay. Cravings are not all bad. Be sure to have a splurge night (or two) each week and go ahead an induldge in a post workout dessert (or glass of wine!), or where ever your craving leads. Often cravings are our bodies way of telling us what we need. The trick is satisfying it without over indulding.
