I might be completely wrong here but isn't basal insulin essential? Without it you run serious risk of DKA.
Our bodies need insulin when we eat so that is why we bolus but our body's are constantly using energy for normal bodily functions and so we also need insulin to turn our stores into energy, albeit at a lower amount.
I would speak with you team about your Toujeo asap. It might be worth, in the mean time, considering the time you inject. My glargine used to be less effective after 20 hours so my bloods would increase.
