Dear Hoppit and Pat
I deleted it because it was getting rather bizarre and I want to avoid the personal issues of various kinds being aired there.

Pat, just to remind you, I am very grateful to you for supplying that information that Gaviscon is known to be harmful, and I have taken this on board for myself and have spread the word to one of my colleages who is treating a patient who takes Gaviscon. So it has been of considerable help. Thanks again.
