Not sure what's going on

I'm not sure what's going on, I had bad heartburn and was put on nexium.  That has helped, but just this past week it came back just as bad as before the nexium.  I'm also not able to keep much food down.  I eat something and it comes up sometimes right aways and sometimes a couple of hours later.  It's like a liquid and just the last couple of days it's coming from my stomach.  Almost like when you have the flu and get sick..that kind of upchuck.  It even happens when I drink water. 

One more strange thing is when I eat anything sweet especially chocolate.  It comes up right away.

Could I have something stuck? or Did my band slip and I just don't know it?

I have an appt with the Dr on Wednesday, so I will bring all this up, but I wanted to check and see if anyone has any of the same. 

Those symptoms sound like you may be too tight. Hopefully that is all it is and the doc can fix ya right up.
