Hey Courtney,
That would've been a hypo, yeah, if you're in the low 4's after sweets... That's what happens when you lower your carbs
and still take gliclazide. With only metformin that doesn't happen. I've had a few, and yeah, they're no fun... But you did
exactly what you had to do. So well done! As long as you're on glic, always have something handy. Like jellybabies or dextro. But if you cut carbs -and truly are a T2- you might be able to ditch the glic, and the metformin, in time. T2's don't hypo, usually. (Still... There are exceptions to the rule. I hypo when it's extremely hot, my bloodsugars bouncing up and down all through the day.). It's usually medication that'll make someone go hypo, either glic and it's bedfellows, or insulin. I was on gliclazide for a little while, but with the LCHF diet I could ditch it, three months after diagnosis. As well as the statins they put me on.
As for granola, yeah... Not the best option. (Personally, I wouldn't go near it.) But your meter already told you as much. If you want to have breakfast-y stuff that's not eggs with bacon and whatnot, there's a keto porridge somewhere on dietdoctor.com, or you could just toss some crushed nuts (walnuts, pecans, macadamia's, bit of coconut flakes), and maybe some berries, into full fat greek yoghurt. Yum, and simple.
And that shouldn't spike you.
https://www.dietdoctor.com/low-carb/keto/fruits has the best and worst fruits listed for a T2. I know it's hard to let the bulk of fruit go, but after a while, you don't miss it so much. And then when you do have a bite of something, it's horribly, horribly sweet, because your palette changes.
It takes a little while, but it's a good change. For me, it made other, non-sweet food actually taste better. More lively, somehow. I really, really enjoy food these days. Where before it was just something I needed to sustain me.
None of us enjoyed handling needles, it's not exactly anyone's hobby (well, maybe some, haha), but you get used to that too... When I started with the finger pricking the hairs in my neck used to stand on end and I'd feel tingly all over. Now it's just pull-out-my-kit, stabby-stab-stab, done. Took about a week or two to get to that point. It's surprising how quick you can get used to something. Good thing too. The good news?
If you're a T2, and you know because you test a lot at the start, what foods do to your bloodsugars, you don't have to test all the time anymore. You'll already know eggs don't spike you, or that granola does, so you won't have to test those: you'll know your safe foods from your risky ones. These days I only test when something's up. If I feel off/ill, if the weather's really hot, if I get a steroid shot, or a flu jab... Or if I ate somewhere and I'm not too sure they listed all the ingredients properly. (Two weeks ago I was served a salad with apple and honey. That did not go well. I was halfway through before I figured it out, and I didn't have the heart to not finish the plate. I walked it off though). All in all... This is temporary. And even if you aren't a T2 but a T1, you could try going for an insulin pump and/or a continuous monitor. That's basically stuck on, and while you'd have to check every now and again to make sure it's all working properly, it would simplify things.
Still... If you're seeing numbers this low on just metformin and gliclazide... I'm keeping my fingers crossed it's T2. That can be managed through diet-only, relatively easily. If that's the route you choose. I know it's what I went with, and I haven't had diabetic complications since. It's been 3 years since my diagnosis, almost, and I've spent most of it on a diet. And honestly, I don't feel like I'm missing out much. And I'm certainly a lot healthier and have more energy than I did before.
In any case, read the Nutritional Thingy in my signature, and be careful with low carbing while on Glic. It's a bit of a balancing act. And you already know you don't enjoy hypo's.
You'll get the hang of this. Good luck with the doc!
