still in it 9 months on from diagnosis,that been said doesn't mean every1 goes through 1 from what I've heard
Well, technically everyone does, but it may be very quick or it may be extremely slow.
The honeymoon period is just a non-medical term for the time from when you first develop an autoimmune attack on your pancreas' beta cells until that autoimmune attack kills off all or most of those cells. In some (especially children) it may last only a few days. In others (particularly older adults) it could last years.
The term was created to explain how much easier it is to manage your levels when you still produce some endogenous/natural insulin. It is much like a couple newlyweds on their honeymoon.... There usually aren't many big struggles at that point in the marriage.
Side note: when I was first diagnosed, my insulin:carb ratio could be as high as 1:50g. If 1unit is too much for you, I'd suggest the Novolog/Novorapid Echo Pen which allows for .5 dose increments.
