Feeling NAUSEOUS after doing the elliptical?

Hey all! I am an avid eilliptical user and use it probably 4 times a week.  Depending on what my workout is that day I use the machine anywhere from a half hour to an hour.  Well, after the past few times of using the elliptical I find myself extremely naueseous.  I've never actually thrown up, but I sure as hell feel like I'm going to!  What's stranger is that the nausea gives way to a heart burn type feeling.  It's happened 3 times so far and only after the elliptical. 

Has anyone else ever had that happen? If not, do you maybe know why this is happening and how I can prevent it?  It's gotten to the point where I'm afraid to use my favorite machine anymore! Any advice would be greatly appreciated

I have had the same thing happen to me. I think it might be your adrenaline. when you start to feel that just slow down and breath.

Good Luck!

Do you drink lots of water while working out? Are you sweating a lot? You might be dehydrated that could cause the naseous feeling. I don't know about the heart burn though.

or it could be from drinking too much water while working out.  Or from eating too soon beforehand!
