I found that I need to take more basal insulin at nighttime (~9 PM) than in the morning (~7:30 AM). The nighttime dose, if basing on time alone, would seem to need to be higher to last longer, but it's just the opposite.
The gosh-darn Dawn effect and the food digesting slowly from the day helps.
My best tip for you is to be patient with adjustments, and make sure to take the dose at the same time every day. Within a couple weeks, you should be at something that you only slightly deviate from. If you find yourself still playing with the doses of basal after a couple weeks, then come back and report so we can offer more dieas.
