Every time I drink mixed drinks (hard liquor and soda/juice) I get a very bad pain in my stomach, centered just below the sternum. It does not happen when I drink beer, wine, or non-alcoholic beverages, or at any other time with food or anything. It also usually doesn't happen if I take straight shots of the liquor. The pain doesn't feel like burning but almost as if I had just been punched in the stomach. The pain comes on gradually and then goes away maybe 20-30 minutes later. Aside from this I have no other digestive problems. I am really curious to learn the cause of this anomaly, I can't seem to find anything about it on the internet. Could it possibly just be a trapped air bubble or something? If anyone knows what it could be or if they have had a similar experience please reply.
