Dabuff is right, likely not hypoglycemia. Pancreas makes insulin in response to ingested carbs. Pancreas also makes glucagon, a hormone which is produced in response to hypoglycemia. The liver makes and stores some sugar, so when hypoglycemia ensues, pancreas releases glucagon which induces liver to release its sugar stores. That is why people starve to death and die of dehydration, but not hypoglycemia when they go long periods without eating. Also, why liver problems can contribute to low blood sugar.
I have heard of unexplained hypoglycemia, but I find it much more likely your symptoms come from high blood sugar, or something else from all the supplements, amounts, or timing of them.
This man knows his shit. Glucagon is always why our brain functions at night.
Some supplements, Divanyll and GMS may cause bouts of Hypoglycemia. I would suggest cleaning up your diet and perhaps substituting insulinogenic sugars for complex carbs.
