You are only slightly making a dent in your bg levels at the moment using the same carb ratio. Up the morning Lantus a bit more so that it has more of a lowering effect at lunchtime and beyond. I would be inclined myself to go upto 17 or 18u and use a carb ratio of 1u to 3g carb just to get my bg levels going a bit lower.
Although you are not eating any carb at lunchtime etc, you are eating minute carb from the salad plus protein from the cheese, meat or eggs etc so you will need some bolus insulin to cover that. Do you drink milk in your tea and coffee, if so that has got to be accounted for either in the basal or in your carb ratios.
hmmm just realised that Ive made a mistake over the above paragraph as you had 3 ryvita (21g carb) and you used the same carb ratio of 1:5. The way bolus/basal works for many is that they usually need more bolus insulin in the morning than they do at lunch because of DP, so use 1:3 to cover breakfast and then hopefully by increasing the morning basal, you will be able to use a 1:4 or 1:5 ratio for lunchtime. The more basal that is used, the less bolus will be needed. Its just a matter of getting the balance right so that bg levels even out better.......
