I take my Tresiba dose at about 6am. Around 5pm with very light exercise (a walk!) my BG tends to plummet to sub 4. I've tested various Novorapid scenarios and even taking my last dose of that at 12 (& running high all afternoon) I still drop low at about 5/6 pm with just a walk. My consultant is convinced the Novorapid should be out of my system and it must be Tresiba and has suggested I swap to taking it in the evening. Reducing the dose just ended up with me waking up high I though Tresiba had a flat profile - has anyone seen anything which would suggest a peak 11/12 hours after injecting?
