Lyn, I would urge you to shun the feeling you "have arrived". In my experience and observation and over the years, those who think they have "it" licked (whichever "it" you choose to apply it to - career, sporting prowess or metabolic syndrome, through to full blown T2, it doesn't matter) stand a much greater chance of running into issues along the line, when confidence in their own self-belief over-rides signs and clues something is amiss.
Focusing on past and current members of this forum (as opposed to any other options I threw into the mix), there is a decent percentage of members who have declared them fixed, and in no need of further support, nor feel the need to stay in the forum, who find themselves re-entering through the revolving door to start all over again, getting back on track. So often they cite having given up testing, or having begun to eat "just a bit more x", and the sneaky, pesky metabolic syndrome/diabetes sneaks back into evidence; whether by symptoms or routine, annual HbA1c.
I was removed from the Diabetes Register almost 2 years ago, and of course, I am delighted with how I have got to that point, and maintained that position, and blood results, but whilst I sometimes expressed myself as resolved, I don't consider that's it. I still watch what I eat, although much of that has become quite instinctive by now. I still test my bloods, and I still weigh myself regularly and check my visceral fat levels to ensure things aren't creeping into areas I need to avoid.
Clearly, it's up to you how you choose to view yourself, but for me, I'll stick with a work in progress, because that's what it is, for me.
