Drink More Beer and save water.

Do more cardio, and do a variety of situps / leg lifts / and exercises for the obliques.

You have to challenge your muscles everytime. Plus, you may already have the muscle it's just hiding under fat. So a good diet could really benefit you.

Here are some text materials I really recommend. my Husband uses them and he has had REALLY good results.

Dear j,
You are not doing near enough reps and sets of those reps, from now on do this.

When you do a sit-up you never come all the way up or all the way down.
Starting position:
Start down keeping your head and shoulders off the ground. Knees raised.

Cross arms in front and over chest.

Raise up only about 10 inches or so go back down ONLY to the starting position (keeping tension on abs at all times)
Now......Do 25 reps which equals ONE set..... Do 10 sets of 25.. rest about 4 to 6 minutes in between each set. Do this AT LEAST every other day
Watch and see what happens....Good-luck AND let me know.
