For several years, I've been experiencing painful stomach gas in the early morning hours. I've noticed that these episodes occur most frequently when I've consumed some sort of dairy within 2 hours of laying down for bed. The only treatment I've found effective is oral antihistamine and any antacid with simethicone. Still I'm held hostage for 2 hours before permitted to return to sleep. Dear Bernie, lactose intolerance can cause abdominal pain, bloating, gas and diarrhea.
Symptoms typically occur several hours after ingesting foods containing lactose.
If possible you should treat your milk with Lactaid before using it. The enzyme in Lactaid breaks down the lactose so that there are no symptoms after drinking milk. Although you have the correct time, I do not think that your symptoms are a manifestation of ulcers. This information is presented for educational purposes.
