Low Blood Sugar?

Weird. My blood sugar was 216 this morning. Obviously, that is too high for a fasting reading. I then took my regular morning insulin shots: 13 units of Toujeo plus eight units of Humalog. I think it was supposed to be seven units of Humalog but I did not think one extra would matter. Anyway, I got on the work computer and totally forgot about eating breakfast. Soon, I started sweating and feeling lightheaded. It was a strange yet familiar feeling so I tested my blood sugar again, and got 88. If my blood sugar falls below 90, I start feeling symptoms of hypoglycemia. It is probably more noticeable since my body has been used to ~200 levels of blood sugar post-transplant due to new medication. I had to find my glucose pills and quickly took two of them, which gave me 8 g of sugar. It has been about 10 minutes and I still feel a bit woozy. My mom is downstairs making oatmeal so I think I should go eat some before I faint (not likely but still).
