Your doctor can adjust all your medications. Work with your doctor.

250–350 is really high, even if you’re taking your insulin and pills. I’d call your diabetes doctor today because your treatment may need adjusting, and if your sugar stays over 240, check for ketones and seek urgent care right away if you have vomiting, trouble breathing, or feel very drowsy.

A Diabete...

You need your Novolog dosage adjusted upward - it's the one that should be leaving you with two hour (post meal) numbers well below 180 (at least initially) and then ideally adjusted to leave you no higher than about 140, 2 hours after you have eaten a meal

Alternately, you could "count your carbs" and reduce them until your 50 units of Novolog is "enough"

But you may benefit from Dynamic Dosing

The Doc can give you a number such as 2 units of insulin for every carb you plan on consuming

So you figure out there is say 38 carbs in the lunch you plan on eating so you would dial up 2 units x 38 carbs = 76 units "for that meal" and you calculate before each meal and "dynamically dose"

In static dosing - your case 50 unit of bolus insulin before a meal - you need to figure out what meal/portion size/how much you can eat "given what 50 units can handle for you" and then you "size your plate" to the static dose, and don't eat that one extra bite because you don't have the "insulin to spare"...

Glucose can stay high with insulin when the dose no longer matches your current metabolic needs. Illness, stress, steroid use, and increased insulin resistance can make it harder for medication to bring levels down. A clinician can help review your regimen.
