What to Do? Age 21 Female, 5'9, 250, Am I a Candidate For Lap Band?

I'm a 21 year old female, about 5' 9" 250 lbs. I've always been a little bigger than my sisters, but within the past 3 years I've gained about 80 lbs that I'm having a hard time losing. I've cut way back on sweets and pop, and have cut back on portions of what I eat. I consider my job my excerise because I'm constantly on my feet and walking. I'm thinking about getting a lap band and tummy tuck but not sure if I'd be a canidate. I would like to have more kids in the future. Any ideas?
