Over The Last Two Weeks I Have Had Stomach Issues

Over the last two weeks I have had stomach issues that seem to relate to eating vegetables and fruits. I thought it may be related to coffee and quit drinking it all together two weeks ago, but the sudden need to use the bathroom within minutes of eating a salad for example is weird. My stomach feels bloated at times even when I haven't eaten much of anything. I started taking a digestive enzyme on Friday of last week and have seen no relief. I called my doctors office and the best appointment they can give me is Tuesday of next week.
