Honeymoon period can cause Insulin levels to fluctuate over time, for some it doesn't last very long, others it can last quite a while. See here........
This length and nature of this phase varies from person to person but honeymooning occurs during the first year of diagnosis and can last for weeks, months, and on rare occasion, for a year or longer. It is not consistent enough to predict if, when, and for how long it will last. And some may never experience noticeable honeymooning.

I wouldn't advise you to miss out on the Insulin injections, but you also need to keep testing to make sure you avoid any hypo's or hyper's and DKA, which can be very serious for a Type 1 until you see your Consultant and discuss.
