There are a couple of solutions: One is an adjustable band that is put around your stomach to temporarily reduce the size of it. It is usually placed via laprascopy instead of being cut open fully. BUT it is restricted to those who are clinically obese. Those without a significant amount of weight most likely won't see much benefit from this band. See

for details.
Another procedure which is being used in Italy/Europe right now is the Intragastric Balloon - essentially a balloon is placed in your stomach and inflated to effectively reduce the size of your stomach. It is for temporary use (i.e. no more than 6 months). I don't think it is available in North America right now, but initial clinical trials in Italy and Brazil are promising. See

That's the long answer.
The quick answer is that NO procedure will be effective in the long term unless you address your diet and exercise habits. You are fooling youself if you think that a surgical procedure will solve your weight issue. Only YOU can solve your weight issue. And, since you will, in any event, have to address your diet and exercise habits, why not give this a try first??? Just a thought...
Best of luck.
