Hi Taiwo,

Thank you for your question. The resource for this is included in module 4.

The CAA mentions the following;

When travelling east the day will be shortened and if more than two hours are lost, it may be necessary to take fewer units with intermediate or long-acting insulin.

When travelling west the travel day will be extended and if this is more than 2 hours it may be necessary to supplement this with additional injections of short-acting insulin or an increased dose of an intermediate-acting insulin.
