Hi!
What you suffer from is probably narcolepsy, which is a neurological disorder. This is thought to be caused by low protein called hypocretin, which is made in the brain. The symptoms are an urge to sleep especially after meals. Sleep studies and EEG are done to rule out other causes of poor sleep and insomnia. Eating light and frequent meals during the day helps. Also assigning a nap time during the day often helps. You can take a light meal before this. At times some ante depressants are prescribed to control the symptoms. Do consult your doctor and get a referral for a sleep specialist and a neurologist. Other possibilities are pancreatic insulinomas causing a surge of insulin production after meals, hypoglycemia and an urge to sleep. In women it can also be due to PCO (of course—not applicable in your case ). Please consult your PCP for primary examination followed by proper referral.
Take care!
Its normal loads of people get it,takes energy for your body to process the food and that can make sleepy hence the term after dinner dip.
