I was put on a mixed insulin dose initially while my endo was waiting for outcome of c-peptide and GAD Ab tests. Made me feel better but not sure it made a huge dent in my BG control, as I didn't have a fixed regime and was traveling across timezones. Once results back and confirmed me as a Type 1 I've been on MDI (basal/bolus) since. More injections, requires more carb counting, but way more flexible. Do ask your diabetic team about this.
Edit for spelling
