Have you ever been diagnosed with GERD? Have
you ever just tried taking a few
Tums? That may work also.
Tums can be very effective, and they are completely safe.
Make sure you are taking the Prozac as prescribed. I'm not sure why you've been "on and off" the Prozac, but that kind of pattern can lead to difficulties in tolerating the med...it can increase side effects, and decrease the efficacy. So, my advice is to just stick with it...take it regularly, as prescribed.
