I would worry about a doctor who didn't tell you.

first: Lantus is long acting and takes a long time to take effect. You
take enough to drop the lowest point in your day to normal. Takes a lot
of trial and error, and you should be very careful not to use too much.
approach the point very slowly, a.s there are a number of variables
which effect you in any given day, and you do NOT want to go hypo

Novorapid begins in 15 min, peaks in 2-3 hours, and has little or no
effect by 6-7 hours. You take this before meals. Again meter, trial,
and error. Be VERY careful. particularly if you are T1. Some TR1's
get huge results from a very small amount if insulin, and some T2's pour
the stuff into the with slow results.

The Novo and Lily sites both have activity curves on them and detailed
prescribing info.

Read that then go to the ABMS website and find a competent Endo in your
area. A doctor who turned a patient loose with questions like yours
should be shot. I patient who doesn;t DEMAND prompt answers that they
understand is asking for trouble.

Thanks for the reply, I do have some knowledge about the way the two
versions of Insulin work. What prompted my question was a posting on
this newsgroup a few years ago which, rightly or wrongly, gave a ratio
to start working from. I have been type 1 diabetic for about five years
now (diagnosed at 67) and have been very successful in controlling my
blood sugars until recently when I broke my neck of femur. After 5
months it has still not healed (blamed on the diabetes!) and it looks
like I am heading for a false hip. I currently have more blood sugar
variation than I had before my accident but I still stay within the 4-8
range about 85% of the time. After all the surgery is over and I am
considered "fixed" I hope the sugar levels return to "normal" but in
case they don't I was looking for a logical approach to determining the
correct doses. I do have a good Endocrinologist who will obviously guide
me but I like to handle things myself and to do that I need to know the
most up to date approach.
Thank you once again for taking the time to reply to my query, which I
now realise needed a bit more explanation.

To properly calculate carb:insulin and other ratios go here:

http://www.insulin-pumpers.org/

The How To pages will have all the information you need to calculate
boluses and rigorously test basal rates. Doesn't matter if you're not on
a pump - it applies to anyone using MDI.

A normal body needs about 0.5u/kg/day of insulin, split 50/50
basal/bolus. YMMV tremendously, there's a whole host of variables.
