Lowest safe BG before bed?

SilverK said:

Had another one. 3.2 at 4pm. No exercise or housework so far today so can’t use that as an excuse. And I had a nap! Almost exactly the same to eat as yesterday, - maybe 2g more carbs at lunch today and a bit more protein.
I noticed I was very cold both times. I’m pretty sure the being cold came before the hypo. Does that sound right?? It isn’t listed as a symptom to watch out for.

Hi SilverK, you're doing well but if you find yourself going low often or having to continually eat carbs to keep your levels up then there is probably an issue with your insulin (too much). Are you a newbie? Make sure you have access via phone to your team and tell them what's going on, they will help you adjust your insulin accordingly. It takes time because they (and you) are just trying to establish the correct dosage pertaining to your normal food. If your normal food is low carb then tell them and they should help you adjust. It can take weeks & months before you get into your own routine and become confident about eating what you want and making your own adjustments. To begin with it's difficult to know exactly how much insulin you might need or how YOU might react so it's very much trial and error based on a fairly (!) educated guess. Yes, being cold can be a symptom as can just about anything else, we share some common symptoms but not others. Again you will come to know your own alerts. x

Hi @SilverK ! As KK123 has said getting it right is a fine balancing act. It's a bit like shooting arrows at a moving target on a windy day as there are so many variables at play. You mentioned you are keeping a food diary and that's a very wise move as it will give you a pretty good insight into how you are reacting to foods and insulin at different times of day.
I've been on insulin for 18 months now and still get my insulin:carb balance wrong, but on the whole manage to keep within my target of 10 to 3.8 mmol about 80% of the the time. I have found that that my insulin:carb ratio varies considerably for different meals and I require very much more insulin per carb for breakfast than for my evening meal. I was taking a basal dose of Lantus that was 20u but have now reduced that to 16u as I was experiencing night time hypos, but the lower dose seems to have more or less stopped those, but if my BG is lowish before bed I usually have a sandwich just to keep things in balance.
You'll get there, it's a bit of a bumpy road to start with but will smooth out after a while.

Thankfully i was approved by the NHS for free Libre sensors & a tester(but i use my phone) about a year ago.
One of the first things i noticed was that my bloods were doing a similar thing to yours overnight.
But i lowered my evening Levemir bit by bit and finally reached the perfect dose so that it didn’t go too low in the night but wasn’t too high the next morning.
But if your Dr or DN wants you to stay on that exact amount of Lantus then it sounds to me that the next thing to try is lowering your evening Novorapid (but only by the least amount you can), until your readings get to a safe level.

Btw, in your earlier post you mentioned having 14 units of NovoRapid 3 times per day, IF that’s correct then it seems a very high dose to be having, if i took that much then my day would be one long hypo or i’d be admitted into Hospital again .
