Hi I have been a diabetic for a long time and generally have pretty good BS readings but about a month ago I started getting some horrendous fasting readings .300-400 range.  My doc advised me to split my evening Lantus into a morning and evening.  I was taking 40 units.  He further advised that I slowly increase my Lantus.  I did that and now I am showing fastings BS's in the 100 -120 range.   Great!! However I am spiking around lunch time to the 200=220.  Then at dinner I am again having good readings even an episode or two of hypoglycemia.  Does any one have an idea to account for the noon time spike.  I am taking Novalog 1  unit to/5 carbs for the meal time insulin

Hi Ralph.  Are you type 1?  I don't use insulin so I can't offer any advice, but there are a couple of members who do and I'm sure they can give you their opinions soon.  Hang in there.

Hi Ralph,

People often have different insulin:carb ratios for different times of day, and insulin needs often change.

If your pre-meal numbers are good then you could try 1 unit/4g carbs at lunch time to avoid the spike. (Check with your doc if you are uncomfortable tweaking things yourself).

Too many variables to determine which areas need to be tweaked without the aid of a logbook. Are you Type1 on MDI? (Sorry, Ralph, can't remember).

Are you splitting your Lantus 50-50 (20 units each dose)? I do 14U Levemir in the evening and 13U in the morning.

As mentioned, do you have an I:C ratio for each meal? Mine is 1:10-1:12-1:8 for breakfast, lunch, dinner respectively and 1:10 for evening snacks over 24 grams of carbs, for example.

Have you done some testing between 2:30-3:30AM? This can sometimes help determine Dawn Phenomenon or if your morning numbers are a rebound high from going low.. Have you tested at the 2-hour post prandial mark to see how you process particular meals?

If you're going low before dinner then RAISE your lunch I:C ratio from 1:5 to 1:6 or 7 (not lower j-web). Do you exercise in this time frame. That could contribute to your pre-dinner lows if you're not compensating for it (i.e. extra carbs for exercise).

Again, and I say it a lot, a logbook becomes invaluable when you're trying to tweak your insulin regimen. Patterns will emerge, I guarantee :-)
