Hi, I am a T1D fro 4 years, currently on MDI with lantus and humalog. I was using tresiba (2 years) till last month. Then due to a different city, different diabetologist, and sudden higher pre-meal levels, I was asked to use lantus. I could have increased tresiba dose, it may well have worked out. But new doctor insisted on using lantus, on the ground of its significantly lower cost and my higher levels with tresiba in past week. Its been over a month with lantus but I have not been able to figure out its right dose, time of dose and whether it should be splitted during 24 hours. I am currently taking it with morning bolus. (I was taking tresiba also in morning). I am continuously getting higher fasting levels in morning (in 250s). On this my doctor said higher fasting can be fixed just by increasing lantus dose by 10 %. Splitting the same dose wont make any difference for fasting levels. I tried raising the dose & I got bad hypos in middle of night. I tried to do simple basal test on initial dose. I noted level increased from 180 to 250 during night. So dose sounds less from this angle. But I am taking full dose in morning. I am not sure what will be the correct way to resolve it. Should I use it in evening instead Or split it in morning and evening Or raising the dose and keep a check on hypos. Any thoughts are highly appreciated.
