For @haforn and @tedbruce in regards to different types of insulin, if you scroll up in this thread to comments in the spring of 2024 some of us were talking about a book that is applicable to this discussion. The book is available from Mayo Clinic Press. It is called The Essential Diabetes Book by M. Regina Castro, M.D. In one of the appendices is a chart of all the types of insulins. I printed a hard copy of it to refer to. It shows an easy summary of things like duration, time of action onset, peak ….. You might find it to be a useful reference tool if you and your provider are considering making any changes to your insulin regimen.
