Hi
@Jane1980 your honeymoon can last any time, mine petered out around a year or so later, it was very gradual though. As Helen has said there are many other factors which can increase your insulin requirements, from illness, infections, stress, exercise, insulin that's gone off, heat, hormones.
The trick with management is knowing when to increase and understanding how to administer corrections doses or increases in basal insulin to cope. It sounds like it would be a good idea to call your DSN for a catch up to run through this with them.
In case you haven't heard of this book it's worthwhile getting a copy to help with understanding more about t1 management, it's 'think like a pancreas' written by a t1, but useful reading.
