I am a new Type 1 diagnosis..less than 6 weeks...44 years young. I am on 10 units of Lantus nightly. Question, many tell me to take it in the morning ans not night...numbers range 44 to 595...slowly coming down.. last night I was 90 going to bed and 52 at 3 a.m. I can feel the low coming on.. also on 1000 metformin and bolus at meals if number is 200 or higher..also, many tell me to take insulin with every meal regardless..4 units... any advice?
You need to find out what your formula is for a bolus. That is how many units of rapid acting insulin do you need for each carbohydrate. I think you overdosed on fast acting insulin for your evening meal when you awoke at 3 am with 52 points. I don't think the Lantus was responsible for the low. What time did you take your evening Lantus shot?
I like to go to bed with 120 to 140 at 11 pm and will snack if necessary to get me there. I take my 11 units of Lantus at 9pm.
I eat a light supper of only 20 to 30 carbs so my last fast-acting insulin shot of the day is only 2 to 3 units. This, I think, protects me against a nighttime low.
I generally awake with around 100. This is my target, anyway. Some times I am only 70. If I am, say, 150, then, I take 1unit of Humalog and delay breakfast for an hour or so.
They say your basal insulin should be 40 to 50 percent of your total insulin intake. If you are using 10 units of Lantus you fast-acting insulin should only be 10 to 15 units daily.
I don't know what the Metformin does to this ratio, but obviously alters it. Why are you using Metformin? It is normally used by Type 2Diabetics. I tried it once to see if it would reduce my lows, by reducing my fast-actring insulin. It didn't work.
You might ask your doctor about what role the Metformin is suppose to play.
