 Study Intervention Visit 1 day 0:- Subjects will come fasting for this visit. Records of blood glucose concentrations monitored by fingerstick and CGM for the previous 7 days will be obtained to assess their glycemic control prior to liraglutide treatment. They will undergo a meal challenge test described below, Liraglutide or placebo injections at a dose of 0.6 mg per day will then be started. No reduction will be made in the dose of pre-prandial insulin boluses and basal insulin if A1C is greater than or equal to 7.5. Subjects will decrease the dose of pre-prandial insulin boluses by 25 and the basal by 25 if their A1C is less than or equal to 7. Subjects will decrease the dose of pre-prandial insulin boluses and basal insulin by 10 if the A1C is between 7 and 7.5. This reduction is based on our experience see preliminary data. Careful adjustments will be made to insulin doses at the discretion of the investigators on the basis of the glucose data obtained from the patients. The target blood glucose will be preprandial 90-120mgdl and 2hour PP 140mgdl, without increasing the incidence of blood glucose 70mgdl. Patients will return to the center after 7 days
