Help...plateau for about a year

Help fellow lap banders...

I have maintained my weight for about a year now and I'm not losing any weight :thumbup:. I got down to 215 at one point and I'm up to 230 now. I need to jump start this wieght loss again. I work out 3-5 days a week and I've been counting my calories. I average about 1500 cal a day but I'm thinking thats too much. Starting today I'm drinking a protein shake morning (316 cal) and afternoon (316) and then having something for dinner (no more than 568 cal) trying to keep my calories at 1200 or less. Is there any other suggestions any of you can help me with? This is really the first time since surgery that I've counted my calories. I am determined to get to my goal weight by spring of 2011...that means I have 70 lbs to go and I need some support from ya'll...
