Hypoglycemia: Symptoms of hypoglycemia include the following: diaphoresis (sweating), pallor, shakiness, hunger, nausea, dizziness, malaise, headache, tingling around mouth or fingers, AMS, seizures. If you eat a sugary substance this is a stimulant to increase insulin which causes the low blood sugar symptoms. If available you could check accucheck with symptoms or see if eating something helps.
