As Ken an Sue pointed out concerning your main part of your post has to be answered by the HCP..
But your Question concerning insulin types..
There are quite a few different types of insulin's
Quick acting, Long acting and pre-mixed of both quick and long acting... These are manufactured b 3 main compaines, each company having a slightly different make-up of there insulin..
i.e 2 main backgorund/long acting insulin's commonly used
Levimer (lilly) and Lantus (advantas (sp))
These two have slightly different PH balance to them, and both have a slitghtly different profile, Lantus being a flatter profile with a shorter tail off..
Both are promoted to last 24 hours (so can be injected once a day)
As you seen plenty to chose from..
Hope this has helped a little
