I am very dec o nrab help

I would try to modify the insulin doses.
At the beginning of my diagnosis I started with 3U and I usually put between 10 and 15u even at festivities or some extreme case I have reached 20u without any problem.

You should first eat healthy and little fat, and meals with little sugar, light drinks, 0 chocolate, honey, etc.

Regular exercise, measure the level of glucose often, go up the dose of insulin, if you see that it is not enough to 4 units, and fast insulin use apart from the slow one.
