@kai My bg levels tend to rise up a bit from about 4am in the morning onwards so although I needed to cover the high at 4am with more Levemir,, I also needed to eat some carb before going to bed to prevent Levemir giving me a hypo about 2-3am. Do you have a 0.5u pen at all as that would help you fine tune the Levemir dose at night and can you eat a snack before bed if you go hypo in the early hours? aSomething like a 5 or 10g cracker with no bolus and then get up about 2am to do bg test and see how high or low bg levels have gone with the increase dose.
Bolus basal is difficult at first but with some determination and plenty of bg testing, you can get bg levels in control.
Why have you transferred from twice daily to bolus basal?
