High Numbers-Basal?

Hi all and Happy New Year!

Around a week ago I experienced some unusually high numbers which were primarily bedtime, fasting and my dinner post prandial. Since my Lantus was on its 21st day the first thing I decided to do was start a new one. But I have been noticing my dinner pp and my bedtime have been a bit higher than I like (nothing like this) for awhile so I read over the threads and decided to try splitting my Lantus which I’d been taking at bedtime (10 units) into bedtime and morning, in case it wasn’t lasting the full 24 hours. Long story short after I started the new Lantus the numbers came down from the extreme highs (a 190 and a 280!) but continue to run high. Thinking maybe that as a LADA I am finally experiencing end of insulin production (I’ve been diagnosed 2.5 years), I have been gradually increasing the dose and as of today am at 7 morning and 6 bedtime, not very much I know, but 13 is a significant percent over 10.

My post prandials are generally ok; except when I’ve been high before the meal (I try and add an extra correction unit). It’s my fasting, before meals and bedtime. Last night my bedtime was 177 and my fasting 174. The fasting is highly unusual for me prior to this week. I had normally run under 100 and was concerned because I’d been seeing some numbers between 100 and 120.

So my question is should I just assume my basal needs are increasing and keep increasing by a unit morning and night until it gets under control? The other possibility is that the new box of insulin I opened is not potent. (It wasn’t still frozen when it arrived). I could call Medco and ask for a replacement. But that seems like it would be a coincidence that this rise in numbers started with a pen from the previous box! Oh yeah and I’m not sick, though I do feel like I’ve been fighting a cold. (I have a weird immune system where I can feel that way for weeks before it goes away or I just succumb. But I’ve never seen any rise in numbers like this even when I actually HAD a cold.)
Thanks in advance for any thoughts!
