I am surprised that you are taking lantus twice a day 4 units.
Lantus is a long acting insulin meant to support back ground insulin requirements, not to cover meals. It is typically given once a day at the required dose.
What is low? Low blood sugar would typically be considered less than 70.
How high is your blood sugar typically? Fasting? After eating?
The best way to put diabetes in remission is through adopting a low carb diet. This diet should be very low in carbs (mostly carbs from non-starchy veges, some nuts, full fat dairy), moderate in protein, and with enough fat that you will not be hungry. Some people find that ketogenic diet can also work quite well.
Hope this helps.
