Marc - This is actually a very common problem, that isn't often recognized as a problem because nowadays people are so goddamn fat that overeating is considered normal.
First, a little more information would be helpful... When you say binges, what are we talking here? 1500 calories in a sitting, 5000 calories in a sitting, etc? Do these binges last for a single sitting, or do they stretch out all day or for many days? How often does this occur? Is it just that you don't feel full and want to keep eating, or do you feel an absolute compulsion to keep eating that is completely beyond your control? etc.
As for quick fixes, anti-depressants might be helpful. Chippewa mentioned SSRIs (e.g. Prozac, Paxil, Zoloft, etc.), which might be worth looking at because (a) as Chippewa said, they can help improve CCK function, and (b) SSRIs are currently the best pharmaceutical treatment for OCD and other compulsion-related problems like anorexia and bulimia. But SSRIs also have problems: they can cause sexual side effects such as impotence, and for some people they can actually cause dramatic weight gain (20-30+ lbs) and increase carbohydrate cravings... so they're not necessarily ideal.
If I was your psych, I'd take a long look at bupropion (Wellbutrin). This is a reuptake inhibitor that's selective to norepinephrine and dopamine, but does not impact serotonin and thus avoids the sexual side effects and weight gain common with SSRIs. Dopamine especially plays an important role in reward, cravings, and satiety. And bupropion is also marketed to help people quit smoking (under the name Zyban). My gut tells me that it might be the ideal antidepressant for your situation.
I'm not saying you should go on an antidepressant, just trying to lay out your options... Other quick fixes are hoodia (as already mentioned) and nicotine. (There's statistical evidence that the rising obesity rates in both men and women are inversely correlated with declining smoking rates.) I'm not saying you should start smoking, but some nicotine gum might be helpful in a pinch.
But for long-term results in treating compulsive problems, research shows cognitive-behavioral therapy (and especially therapy paired with medication) is more effective than medication alone. If you're really concerned about this problem, see a doctor, but not just a general practitioner or even a general psychiatrist. Rather, you should see a psych that specializes in eating and/or compulsive disorders. They are qualified to deal with this type of problem; most MDs are not.
All that said, if your problem isn't severe then I strongly suggest that you buckle down, summon your willpower, and make a concerted effort to change your behavior. When it comes to overcoming compulsions, the old adage that "practice makes perfect" holds true. There is research showing that once an individual is able to resist a compulsion, and continues to do so for an extended period of time, the "pathways" in the brain that are driving the compulsion actually become weaker until the compulsion is eventually eliminated. In other words, resiting the cravings will require real effort at first, but eventually it becomes much easier until the cravings subside altogether. If you go see a psych for cognitive-behavioral therapy, this is in essence what they will have you do, so you should try doing it on your own.
I hope this helps...
