How do you discreetly check blood sugar when in public/not at home?

So I really want to get more committed to taking control of this. I’m still pre-diabetic, which means my insurance (Medicare) won’t pay for a CGM, and I am not eligible for coupons (please don’t fight me on that, I’ve already looked into it). I am low-income, and even the $75 or $89/month is too much for me.

But my finger-stick monitor, test strips, and lancets are FREE on my insurance! So it just makes more sense to do it that way.

But…2 hours after breakfast, I’m usually at some sort of appointment or just not home. Same with lunch if I’m just not home before/after. I am pretty good at checking around dinner, unless I have some sort of event. And of course I do check my morning fasting glucose every day.

Where do you go to check? Maybe a bathroom? Is that sanitary?

I’m on disability so I don’t have like a desk at work or similar.

I really want to take this seriously, but I feel weird pricking my finger in public.
