Hi Liz and welcome to a whole new lease on your life! You'll find tons of helpful information on this site.
It sounds like you have a doctor who is willing to help you go low-carb and reduce your meds proportionately as needed. If so, that is wonderful...especially since you're already taking insulin. Going low-carb while on insulin is much more difficult because the medication CAN make your blood sugar go dangerously low. But, it is NOT the low-carb diet that is dangerous, it is the injected insulin that is dangerous.
Unfortunately tho, many T2 diabetics (even those who are not yet on insulin) wind up having to fight their doctors who advise against low-carb... until the patient finally proves to the doctor that this WOE works.
My husband is T2 and, in fact, his diagnosis was the impetus that got us both into low carb. You can read about it in my journal if you're interested. Upon diagnosis, Hubby's doctor just told him to watch his diet (with zero advice on what to watch out for except that he should not eat too much sugar....well, DUH!) Doctor just put Hubby on a couple of oral medications and told him that, if he couldn't get his HbA1C (then 12.4) down to around 7.5 to 8 within 3 months, he'd need to start insulin therapy.
Three months later, after we figured out for ourselves that it is carbohydrates of all kinds - even those from the so-called "healthy whole grains" - that are the enemy of diabetics, Hubby went back for his 3 month check up and his HbA1C was down to below 6.0! His doctor was so surprised he was certain the lab must have made a mistake so he made hubby come back in for a second blood test.
3 1/2 years later, Hubby and I are still low-carbing. Hubby is off ALL diabetes medications and his most recent HbA1C was a perfectly normal 5.3. In other words, if he went to a doctor who did not know his history, the doctor would have no way of telling that Hubby is diabetic. Cured? No, because if Hubby went back to eating a SAD (Standard American Diet) his BG would very quickly go hay-wire again. But, as long as he doesn't ingest too many carbs, he might as well be "cured." He no longer has any greater risk of going blind, suffering neuropathy, having a heart attack, losing a limb to amputation or any of the other complications of diabetes that does a non-diabetic. And that is cured enough for us!
At first, when Hubby told his doctor at his 3 month check-up that he had begun following a low-carb diet (less than 30g of carbs per day) the doctor insisted "you NEED more carbohydrates for energy and to keep your brain functioning, all the fats and protein you're eating will kill you if you keep it up!"
Then, as Hubby's HbA1C kept going down and his lipid panels actually improved, and his kidneys showed no damage from too much protein, the doctor started saying "well, what you're doing seems to be working for you....but let's keep monitoring things." Then he decided that maybe Hubby's diabetes was just responding exceptionally well to his oral meds so took him off of them to try to prove to Hubby that it was NOT our diet.... warned us firmly that Hubby's BG would probably go up so keep testing BG EVERY day and to come back in if he saw ANY readings over 150. (BG did not go up. Seldom saw any readings over 130 and then only when hubby occasionally deliberately splurged and even those few high reading would drop down within about half an hour.)
Now that Hubby has been off all his diabetes meds (even metformin) for over a year and is still doing great, we notice that Hubby's doctor NOW has a ton literature about low-carbohydrate diets for diabetics available in his waiting room.
And he has even cut Hubby's HbA1C tests back to just twice a year instead every three months.
