I have 2 questions/problems.First one started about 2 months ago. For no reason, I randomly start coughing, especially in the morning, and it doesn't hurt but it feels really uncomfortable, and I end up building up gas whenever this strange cough happens, and I have to "burp" it out. But for the past week, whenever this certain cough happens, I start to feel like throwing up all of a sudden really badly. My mouth gets very watery, and I become very uncomfortable. However despite this feeling occuring everyday last week, I haven't thrown up yet. I'm worried that something is very wrong. Any ideas? I think I might go to the doctor's today, because it feels really bad.Second problem is, my heart is beating unusually harder and faster these days, especially whenever I'm not with my girlfriend. However, when I'm with her my heartbeat is more normal. Is this anything to do with being "in love" with my girlfriend? Because since we started to tell each other "I love you" which was about 8 days ago, that is when my heartbeat has become a lot harder and faster when I'm not with her. It definately does not hurt, but it can be quite uncomfortable sometimes.Edit:I just told my mom about the coughing thing and about how I felt and all the symptoms I was having and she told me that I have exactly what my dad has. She said it has something to do with acid in the esophagus. The reason why I get it mostly in the morning she says, is because I eat quite a lot before I sleep. So she told me to not eat after 9:00 PM, and to not eat as much fatty foods as possible.Can anyone confirm this? Especially before I schedule a doctor's appointment. I still have no idea with the heartbeat thing, but keep in mind that she is my first serious girlfriend and I love her very dearly.
