During the day I am fine. At night, I get stomach aches concentrated on my left side. To get releif, I have to get up or sit up for a while, then I go back to sleep. But in another 2-3 hours, like clockwork, same thing. I have had type 2 diabetes for a long time. My primary care doctor thinks I may have gastroparesis, but in a forum, people with that condiiton report much worse symptoms than I have, and they don't just say they have problems at night.
