Population: Compared for placebo versus BCQR after 4 weeks of treatment.

At the end of each 4 week intervention period, we will measure the brachial artery distensibility as a measure of vascular stiffness by Dynapulse (%/mmHg). A larger number indicates less stiffness (ie greater compliance).

PRIMARY outcome

Timeframe: 4 weeks

At the end of each 4 week intervention period, we will measure the reactive hyperemia Index (RHI). The Reactive Hyperemia Index (RHI) measures increased bloodflow after vascular occlusion. Higher scores indicate lower CVD risk and a better outcome, Scores of less than 1.67 may be considered abnormal. Scores of 1.67 1.67-2.09 may be considered borderline, and scores of 2.10 or higher my be considered normal.

Timeframe: 4 weeks

At the end of each 4 week intervention period, we will measure the effect of Bromocriptine Quick Release on glycemic variability throughout the day (mg/dl), measured as SD of all glucose values throughout the last 7 days of intervention. Incorrectly initially entered as primary outcome. per protocol this has always been a secondary outcome.

Timeframe: 4 weeks

Population: Unadjusted least square means by mixed procedure.

At the end of each 4 week intervention period, we will measure Hypoglycemia Awareness using the Gold method (7 point Likert scale: Possible scores range from 1 to 7. higher scores indicate more impaired awareness of hypoglycemia, and a worse outcome), Clarke method (8 question questionnaire characterizing hypoglycemia awareness. Possible scores range from 0-7, with higher scores indicating less awareness and a worse outcome), and the McAuley score (list of symptoms with a 7 point Likert scale for each. Possible scores range from 1-7 for each item, and are averaged across all symptoms, for a total possible score range of 1-7, with higher scores indicating more symptom awareness, and a better outcome). Incorrectly initially entered as primary outcome. per protocol this has always been a secondary outcome.

At the end of each 4 week intervention period, the % will be measured by SyphgmoCor. The Augmentation Index measures vascular stiffness by comparing pulse pressure of the reflected wave to the primary wave. HIGHER scores indicate greater vascular stiffness and higher cardiovascular risk, but a normal range has not been clearly defined. Presented as AI normalized to a heart rate of 75 (AI75).
