In regards to "At 2am he was shaky,sweaty,and weak" these are signs of hypoglycemia, low blood sugar. You should call his doctor immediately as his dosage may need adjustment. ONLY his doctor should be the one determining the amount and time of his medication/s, not strangers on a public Internet health forum.
Also, next time this occurs test his blood sugars. If low give him a half a glucose tablet, or half a glass of orange juice, or a piece of hard candy to raise his levels. Don't overdue it. Good luck -
when did he get the humalog ?
