New reflux problem? Help

I was diagnosed w/LPR over a year ago and was put on Prevacid and acidopholus. Recently I was taking 15 mg 2x/day. I ran out of my Rx and I had to cancel my insurance. I got samples from my doctor. When those ran out, I had him call me in an Rx. But 30 pills were $179 (w/out insurance) so I didn't get them.
I have been off the meds for about 2 or 3 days.

I think I have major acid right in the middle of my chest. I also keep burping and my stomach is upset. I have some diarrhea. I don't know if these are connected.

I recently (like a week ago) changed my diet to healthier things (cut out some sugar and simple carbs) as was told by a dietitian.
My diet has, for quite a few months now, included yogurt, so I stopped taking acidopholus.
When I was originally diagnosed, my problem was a vomiting feeling in my throat...not an acidy feeling but just the feeling right b4 you throw up.

Now, I have this burning in my chest; I assume its acid reflux??
I just got some 30 mg samples from my ENT...he says to take 2x/day (so double what I had been taking)
Could this stomach thing be something else or is it definitely reflux? I went home early from work b/c I felt so crappy.
Please, anyone help.

Thanks

There was recently an article on msnbc on how you could use natural remedies to treat acid-reflux instead of relying on pills and antacids. You can see the article here.

There's also a video from the Today show featuring Dr. Leo Galland, who talks about how things like carrot juice and licorice can help treat acid-reflux. He also discusses other foods people can use in their diet as natural remedies to the problem.

Because pills are so expensive and they cause side effects, I think the natural remedies are definitely worth a try. Hope this helps.
