Can sugar free hawaiian punch cause heartburn?

I have been having a little bit of heartburn, nothing bad, but sometimes I'll take a couple tums to help. I have been drinking sugar free hawaiian punch lately instead of my usual crystal light because it was on sale (trying to save some $ ) and noticed that it seems to happen when I'm drinking it. Does anyone else have this issue or know something about it?
I'm not too tight so I don't think it's that.

I've noticed that Propel gives me a little heartburn a little too often and Crystal Lite does, sometimes, too, so I guess your HP could do the same to you.

I know that the Crystal light lemonade flavor gave me heartburn but none of the other crystal light flavors did. I guess I'll stop the hawaiian punch and see if that's it.

Isn't it funny that certain weird things cause heartburn?  I know iced tea will give me heart burn - and I dearly love iced tea.  Any kind, any way... and as mentioned - so does some propel.  The other weird thing is Aquifina water - I can't drink it no matter what - it gives me terrible  heart burn - weird huh?  I can drink the Sam's Club water -and Dasani water -but Aquifina gives me heartburn everytime.  I would just stop it for a few days - see if it goes away -then test it and try it again... you should know.  Anne

I never get heartburn so it's definately odd for me. Strange that Aquafina gives you heartburn.

Oh, I am so glad that you posted. I get heartburn only when drinking water and come to think of it I haven't tried a different type because I have googled and searched and can't find anything on water causing heartburn......I was going to get a slight unfill on the 9th.....

But I don't get heartburn at night, or from eating spicy foods even hot sauce but if I drink water and or haven't eaten in a while I get heartburn mostly in the afternoon.

Strange, but I am so glad you mentioned it because I am going to try a different type of water.......I drink the filtered water from my refrigerator......it is well water that is treated with salt due to the hardness.......maybe it doesn't filter out enough.

Anything with copious amounts of red food coloring (or ANY food coloring, for that matter) gives me wicked heartburn.

I'll check that out cause I know it's definately more of a solid color than the crystal light I was drinking usually is. Thanks for the info!
