“Roller coaster” blood sugar days happen to the best of us. Wild fluctuations from high to low and back again are sometimes just part of life with diabetes, but that doesn’t make them any less frustrating. So how can they be handled without losing your mind?
The answer is simple, and probably a bit unsatisfying: I just take the highs and lows as they happen. Rather than dwelling on the literal big picture of ups and downs that my CGM displays, I decide to treat each instance uniquely and have faith in the fact that everything will stabilize eventually.

For example, a recent weekday started off wicked badly for me when I had a low blood sugar at around 4 A.M. I did the thing that you’re not supposed to do and totally over-treated it (whoops), resulting in me having to take insulin to counteract the carbs. Well, I didn’t take quite enough insulin, because I was pretty high still when I woke up again a couple hours later. I took an aggressive bolus for the high and did my morning exercise routine…
…which backfired on me because soon after completing my workout and eating a quick breakfast, I was dropping like crazy. I’m almost certain that most other T1Ds would agree with me when I say that having a low blood sugar right after eating (and taking insulin for said meal) is SO obnoxious. I knew my carbs would kick in eventually, though, so I opted to suspend my insulin and went about getting ready for work…
…only to be sky-high again when I arrived to the office. I took another big bolus, knowingly stacking my insulin but not caring because I just wanted to get my blood sugar down…
…and that absolutely worked like a charm! By lunchtime, I was low again and literally eating frosting out of a Tupperware container (don’t @ me). Usually, I have zero restraint when it comes to sweet things like frosting and I was worried that I’d gone overboard with my spoonfuls of it. But magically, the low/high roller coaster stopped for the rest of the day after that! In fact, I was level between 90 and 110 for THE REST OF THE NIGHT.
I’m not saying it was worth it to deal with the incessant ups and downs all morning and part of the afternoon; rather, I’m trying to point out that I just did what I could in order to get off the roller coaster ride and it paid off by the day’s end.
Sometimes, with diabetes, it’s more important to focus on blood sugar in the moment rather than stress about what it did or what it’s going to do. That way, I find that I can help treat my diabetes the way it needs me to treat it then and there rather than trying to anticipate what it might do later on. It’s all about perspective and remembering to keep it simple, even if it doesn’t always yield the fastest results.
