i would agree that this could be hypoglycemia or at least hypoglycemia can cause this symptom. i'd recommend getting your husband to a doctor (i know that is easier said than done sometimes). this issue and the chest pain should be looked at. just schedule a regular physical and inform the doctor of these symptoms. good luck
what can cause extreme drowsiness related to hunger? . my husband is 34 has smoked cigarettes since he was about 15 and has recently started getting extremely drowsy when he gets hungry. it is uncontrollable. no matter what he will fall asleep when he gets hungry. after he eats he is back to normal. he was having chest pains pretty frequently for a while but since things in our life have calmed down a tad those chest pains have not reoccurred. it's been several weeks since he has told me that he had chest pains. . could this be hypoglycemia?
