Constant feeling of the need to throw up. Any suggestions?

I had my surgery 6 years ago, and the last 2-3 months I have more days I can't eat than days that I can. I can get about 6-10 bites in. I am eating smaller than small bites. today lunch was cottage cheese I am doing everything I can to keep it in. I don't know if it is a slipped band or what. I have no stomach pain and on days that I can eat it is good not an overeat or anything just normal lap band eating. I had dinner last night at 5pm and at 730 was still struggling to keep down a liquid. HELP!
