Whatever it was, it's gone now. But for the last four days I've wondered everything from a bad site to bad insulin to hormones to a virus and everything in between.

It started overnight Wednesday (I think) when i was in the upper 300s for no reason. I went over dinner in my head over and over to make sure I hadn't missed anything. While I had had mostly good numbers with that site, I considered that it had gone bad or that I was beginning to need to change my sites more often.

But after changing my site on Thursday I continued to have horrible blood sugars, and was certain I had a bad site. With my recent experience with worn out sites  -- shooting up the second I start eating something, spiking high and low -- I thought I might have gotten an old site.

So Friday morning I changed my site again! It wasn't until I woke up with a horrible headache that lasted all morning and wouldn't respond to any treatment did it occur to me that I may be getting a bug and that may have been what was causing my blood sugar to go haywire.

After I embraced that theory I more or less lived with the nasty blood sugars, but watched them like a hawk with Dex (thank goodness for Dex!). I wanted to make sure I didn't go low on a quick trip to the park with the rugrats, but a 25-gram granola bar that I can normally eat without issue sent the arrows on Dex straight up. I couldn't even have four SweetTarts to fight off an impending low without spiking.

Even though I anticipated getting sick and knew that the crazy blood sugars were not my fault, I got thrown for a loop again when three nights after dinner and toward bedtime I was trending so low that I wondered if I had over bolused and if I needed to change my basal rates.

But last night things changed. I was again trending low at bedtime so I headed downstairs for some milk. I was worried that just about anything was going to make me spike. I worried that I wouldn't be able to go for my walk in the morning because a spike would make me high all night. But after chugging some chocolate milk and heading back upstairs, Dex still showed me trending low. I tried to be patient, but that wasn't going to happen. So I slowly had a few SweetTarts.

And this morning, I woke to a nice trend graph on Dex, a decent fasting and was able to go for a great walk. I nervously watched Dex this morning after breakfast (especially since I changed my site this morning) and was absolutely thrilled to see my blood sugar behaving. I had to fight off two potential lows today and loved seeing the trend graph on Dex stay under 200 with no spikes.

It's so hard to not blame ourselves when blood sugar goes crazy. I don't always get crazy blood sugar signs when I'm getting sick or when I'm hormonal, so in a way it was actually nice to have this happen so I could play detective. It felt good to know that I was doing everything I knew how to do to keep my sugar in check and that in this case diabetes just wasn't cooperating.
