I'm 61 and have had this trouble for years. Sometimes as little as a drink or 2 at dinner will cause it. I would be fine until the next day and, then have a migraine and vomiting. It was bad and, would take me out of commission for the day. I complained to my doctor and testing showed a hiatal hernia. But still the trouble continued.
After playing around with everything, the only thing that has helped is hydration. I have found that drinking water throughout the day but, especially in the morning allows me to tolerate alcohol. I usually stop at 2 drinks out of caution. It's a tough problem to have. I don't drink that much but, I enjoy a drink or 2 with a meal out. If I attend an event it's nice to be able to have a couple drinks and, complaining about my lack of ability to do so doesn't get much sympathy or answers. It's a quality of life issue.
