                        I am wondering the same thing because I have been  diagnosed with migraines, which are as much GI  symptoms (e.g., nausea), as headaches,   which usually (but not always) hit me after  drinking 2 glasses (and sometimes less)   of wine or beer. The symptoms don't show up   12 hrs after, but they wipe me out for a day or more.   Have you found out anything about this?
