Stomach problems... anyone??

So I have a few issues with my stomach, I get a lot of heartburn when and when I do not eat, I wake up in the morning with the feelings of acidity in my stomach and for the past two weeks I get an odd pain in my stomach after I eat, like the food was tainted but it's not. I also get a problem when I drink alcohol [no beer, generally sweet liquor] and after my first or second drink I get a pain in my stomach like its tightening into a small ball, which usually goes away after about 20 minutes - it seems to happen all the time so I expect it now - though the other day after having one Smirnoff Raspberry drink, I felt the same pain then all of a sudden it felt like i had a hot flash, like fever and chills then I felt nausea and well, you know - then after I ate I felt better. It was the only time that happened. I'm no where close to an alcoholic and I don't know if they're tied in together. I was reading about gastroenteritis, acid reflux and gall stones but none seem to match my symptom
