Crossposted with the last two posts before my last one.

They have a meter but are almost out of test strips. They aren't able to test while on the road, and will have to wait until they're done being on the road for a few weeks, which isn't going to be for a couple of months.

Again, I'm seeing recommendations for taking in juice and fruits. Are these ok? They seem like they're very high in carbs with a high glycemic load.

That was another thing that was confusing. There are people recommending only having foods that have a low glycemic load, but another site said that even foods with a low glycemic load (complex carbs, essentially) can cause a spike a couple of hours after eating if the body is also insulin resistant during the secondary insulin phase. More conflicting advice.
