YUCK (BEURK for stéphane, though the brits will probably misinterpret that ) I tried a gaviscon tablet once.. before getting on my motorbike... 5 miles down the road and had to stop as I was literally foaming at the mouth (all yours Phil, do your worst). If the idea is for the tablets to make you physically sick then they work!
I used to have acid pretty much permanently and ended up going to the doctors (first time in 10 years) just to be sure. Apparently it's all to do with the stomach lining and if you're not careful it becomes a bit of a vicious circle. So I'm with Simon on this, to try and get matters back under control you want to consider your diet carefully (avoid anything fatty and/or acidic, ie fruits, dairy is a tricky one), drink lots of water and check to see whether you need to lose any weight. I've been much better since taking these things into consideration... just got to try and manage stress and sleep levels now! In my experience, coffee seemed to have little to no effect.
