I also have reactive hypoglycemia and I tried the potato diet out and had zero crashes the entire time. It's just not possible (for me) to eat enough calories, quickly enough, to cause a crash. I was only on it for a few days (~5), precisely for the logistic issues that the article and the original diet post discuss - I couldn't cook and eat enough calories to not be absolutely starving after the first couple days.

I've never seen any literature supporting that the feeling of tiredness and fatigue after a meal is the direct result of blood sugar levels. Mostly what I've seen is just conjecture online, and correlational anecdotes about eating high glycemic index foods and feeling tired. Not discounting people's experiences, but trying to suss out the science here.…

There's another thing, called 'idiopathic postprandial syndrome' which is essentially the symptoms above, but without actual low blood sugar (Talking with endocrinologist, they say that the insulin sensitivity for most people is much higher in the AM and daytime than at night, so it makes sense that you might have more problems in the afternoon, but you should probably talk to a doctor rather than taking my word for it!
It's often difficult (in the US at least) to get primary care and endocrinologists to take you seriously if you are not actually dying of diabetes or passing out from low blood sugar - this is where dipping into the realm of concierge medicine can be helpful, or at least, it has been for me. They are often much more willing to investigate thoroughly.
