Moderation in all things?

I'm not a doctor, nor do I play one on TV, but in my humble opinion, allowing yourself to enjoy your vacation and staying under 150 during that time shouldn't be a concern. Those are still fairly low numbers for many. I used to regularly stay under 140 but as things have progressed, I now run between 110-180 but my A1C is still under 6.5 so my doctor doesn't seem too concerned about the slight elevation in BG readings. Even having cake & ice cream yesterday only raised me to 209 and I was back under 120 when I did my fasting test this AM. Now if I was constantly 180 or higher, I would probably be concerned.

This brings up a question I have been wondering about. I was on vacation this past week, and did not watch my diet as well as I should have. OK let's be honest, I really didn't watch it much at all. I checked my bg levels about 3 times per day and it never was sky-high, but stayed under 150 every time I checked it. Does going "off the wagon" for a week do damage or if you get back on the diabetes plan when you return do you minimize any damage you may have done?
