Adjusting your diet to multiple small meals may address the issue, as you have stated. This site may have useful information on this topic: https://www.niddk.nih.gov/health-information/digestive-diseases/gas-digestive-tract/eating-diet-nutrition. Wish you good health!

Since you have no other digestive symptoms I would only be concerned if you're experiencing unintended weight loss. Drowsiness after meals ( usually large ones) is caused by circulation being diverted to the digestive tract & away from the brain. Try avoiding gassy foods& beverages. Taking simethicone 1/2 hour after eating can prevent bloating from gas buildup.
