The purpose of this study is to test whether using extra doses of aspart insulin to correct blood sugars before meals improves the care of patients with type 2 diabetes in the hospital who are already receiving the standard of care treatment with glargine and aspart insulin injections to control blood sugar levels. Studies done in the past indicate that blood sugar levels are controlled on the standard treatment of insulin and that most patients do not need the small extra dose of insulin at bedtime. The investigators want to test if there is any benefit to giving patients extra doses of insulin during the day to correct the high blood sugars.
