This sounds a lot like what I'm going through. I'm type 2 IR but may be headed toward type 1. I find that my bs will be high for several days and then suddenly get some near normal and low numbers for a few days regardless of the dose. The same thing happens after meals. I can eat a meal of baked chicken, kidney beans and a cup of berries with bs at 117 before and 147 2-3 hours later. 3 days later I can eat the same meal with a bs of 120 before and suddenly have 299 2-3 hours laters. Then the next day I will see numbers of 60-120 the entire day. The numbers are all over the place. Lows for me at numbers below 80. I once went to bed with bs at 175 and woke up with a 49 at 2:30 in the morning. My fast acting dose is 7-9-12 units before each meal (Novolog) and my long acting is 75 before bed (Lantus). I find that units below 9 do not seem to help much. My typical meals are: Breakfast: sausage patty and lite yogurt; Mid-morning snack: bananna and peanut butter (or a handful of nuts); lunch is soup (usually Chicken or vegetable) and an apple (small); Mid-afternoon snack: bananna; Dinner is usually chicken, lean beef, or lean ham with a vegetable (squash, green beans, etc), and a cup of mixed berries (strawberry, blackberry or raspberry). My last aic was 8.5 and I'm postive the next one is going to be higher.
I also wondered if what Jeannie posted in another topic might have something to do with my numbers. In her post she said something about changes to her diet and weight loss and seeing higher numbers in the morning. I joined a gym a few weeks ago and have dropped 5 pounds in 1 week but that week my numbers were higher. My trainer said this might happen for a month or two (he's also diabetic).
*Sigh* will keep everyone posted.
I'm type 1. I take around 36-38 units of Levemir in the morning and before going to sleep. Then I take something around 14-18 units of rapid acting Humalog before lunch and dinner depending on current BGL. Add to that less than 10 units for breakfast and evening snack. I do realy get lows during the night, but it must be the insulin resistance I've been diagnosed with that makes things a little bit unpredictable. It's like some foods stayed in my body for longer periods (2 days) raising my general BGL, but when that's cleared with extra doses of insulin, I start hitting the lows even if I lowered the doseage..
It seems that for a lunch that has low levels of carbohydrates, 10-12 units would have the desired effect on blood glucose, but this dose would have to be considered a minimum. Less than 10 units does not seem to have much effect at all on me if I'm already heading for high BGL and for a normal sized meal I end up injecting at least 16 units and can easily maintain blood glucose levels up to 6-7 hours later with no snacks in between.
So, if I calculated correctly, I'm injecting 124 units a day on avg. That's over 1.5 units for each kilogram I weigh. Even so, my hba1c was 8.1 few months ago. It's not completely out of control (for a type 1), but could be better. If I lowered the base Levemir, it would be worse. Tried and tested..
