Primary Outcome Measures:
  • Percentage of time CGM glucose is <70mg/dl [ Time Frame: the subject will be followed for 9 days ]
    The percentage of time CGM glucose is <70 mg/dl during the basal glucose evaluation


Secondary Outcome Measures:
  • Percentage of time CGM glucose is <40 mg/dl [ Time Frame: the subject will be followed for 9 days ]
    The percentage of time the CGM glucose is <40 mg/dl

  • Determined hypoglycaemic episodes [ Time Frame: the subject will be followed for 9 days ]
    The percentage of subjects who perceived all CGM determined hypoglycaemic episodes

  • Weight gain [ Time Frame: the subject will be followed for 9 days ]
    The mean weight gain since initiating basal insulin fromo retrospectively gathered data.

Detailed Description:
In many clinical trials, basal insulin is titrated to only a fasting glucose goal. The usual final dose is >0.4U/kg. In carefully CGM monitored/titrated studies in both basal insulin alone or in pump-treated T2DM, we have found the basal insulin dose to be <0.3U/kg. This suggests that if guided by a single daily fasting glucose, titration may result in an excessive basal dose. This study will examine that issue.
