How does long-lasting insulin work?

Question

I used to use regular short-acting insulin and would take multiple shots over a day as my blood glucose fluctuated. Now I take one shot and it lasts all day. How does that work?

Type 1 diabetic here. The long acting, like lantus, keeps your sugar stable but won’t compensate for a sudden large amount of carbohydrates like fast acting insulin like humalog will. I can survive with just the long acting if I watch what I eat, but when I lost my insurance and only had short acting I wasn’t able to maintain and ended up with my blood turning acidic.
