Insulin for type 2 is a stopgap for you to get going with meds like metformin, getting a handle on improving your diet and increasing your physical activity.
Personal advice, start taking melationin and trace minerals. Melatonin reduces inflammation, and it up regulates the individual insulin receptors making each of them more efficient. I know several folks who got of the meds eventually, just with melatonin, diet, exercise, and keeping track of their blood sugar along with frequent doctor visits.
Metformin should be your first try for meds, as it is an anti cancer med that was re-purposed to this use, and has shown to be associated with slightly lower cancer rates in people who take it.
I'm type 1 but I gained 10% body weight first 30 days on Lantus, and gained another 10% over a few more months, then stabilized 20% higher. Truvia, and Basagular both can do that too, and the Truvia has some other kind of hormones, or weird biotech chemicals in it. Type 1 is a separate thing, but it is managed similarly and has similar health risks.
Type 2 is an inflammatory overload on your body, melatonin is the body's main antioxident, but it declines throughout life starting at puberty, and gets below the load in your 20s. You can't reverse time, but you can restore your body to less inflammation and up regulate your body's use of what insulin it can produce.
Also eating less animal products and more plant based foods can lower the risks of complications, and has been shown to reverse the condition through switching to more nutritious foods.
If you want to come off insulin, you will have to track your blood sugar, to be able to diagnose when your running low, and slowly adjust your dose down making sure you stay under 160 post meal and between 75 & 120 before meals.
