Tresiba
"I have not seen Tresiba do much of anything. I was on Lantus @ 60 units 2 sX daily, along with Metformin 1000mg 2 X daily and Victoza 1.8 mg 1 X.
I switched from Lantus to Tresiba @ 70 units daily, maintaining my other meds. My morning readings sky rocketed from 85-140 to 275- 340. My diet stayed basically the same. Over a period of 4 to 6 wks, I increased the Tresiba slowly and am now up to 110 units daily. NO CHANGE !!! THIS IS CRAZY. I'm going to try one more increase to 120 units. 
I had to stop Lantus b/c my ins comp (PPG / CVS- Caremark) decided not to cover Lantus."
