As a Crohn's patient for 40+ years (the first diagnosis was Ulcerative Colitis) I would say that you have some good tips here. I would look at stomach problems and rule them out, because this does look like a stomach problem. If none of this pans out, go to the old home remedies like diet and teas before bedtime. Also the acid reducers (stay away from the PPIs). I take Famotamine, 20mg. every night. Maybe the stomach can't handle the morning acidity. Just my thoughts.
