Yes I have meds I am on metformin , and basel insulin
You are probably right, but he is on basal only not basal/bolus so he is not injecting for specific meals just for background cover (through fixed doses?).If you are on insulin you need some one-on-one coaching/training from a trained medical professional ASAP if you are not getting it already.
No medical professional would send you home without giving you an indication of the Basal dose that you need to be taking. What amount of insulin are you taking if you have "no fixed" does and when are you taking it?No fixed dose
