It is hypothesized that, compared to Routine Care (RC), GEM with CGM (GEM+CGM) administered to adults with t2d who are failing with oral medication management will result in better diabetes control (lower HbA1c), reduced medication management (less medication), and better psychological functioning (e.g. greater sense of empowerment) in the short term (3 month follow-up). Further, it is hypothesized that their reduction in HbA1c will be driven by a reduction in PPG.
