You might need to investigate adjusting timing and size of dosage. Do you take all 60mg before breakfast? I take 100mg per day, but only 20mg before breakfast, otherwise I'm hypo by lunchtime. Everyone's metabolism is a little different -- you may need to tweak timing and dosage until you find the combination that works best for you in keeping your sugars stable. My DN encouraged me to take control, test and adjust dosage accordingly.
The good news, though, is that your pancreas is still in good shape, so all the more reason not to strain it by taking more meds than you need. Good luck!
