Random highs then lows

I was wondering if this has happened to anyone else… The past couple months my sugars have been running higher than average… Last week though it spiked up and would sit between 170 and 260. I have not been sick or stressed that i’m aware of. Then a couple days later my sugars keep getting low and i have to eat about 40 or 50 extra carbs to get it to stay above 140 (if i’m going out or something). Note that i didn’t change any of my insulin doses or anything.
Any ideas? I go to the endo’s office on Tues.

If you were female I’d say it was your cycle - I always run high for a week then drop too low for about a week. Maybe you had a bug you didn’t know about? Changes in activity levels? the D has a mind of its own…

I had 2 very lows last week, and then came the highs out of nowhere. I don’t know either whats going on. We have had coler weather, snow and ice, not sure if my body reacts to the cold like this…I hope you can find out:)
