It was this...
Ranitidine is not currently available in the UK or globally.
I had some in he cupboard until recently.., 4 years old and I still used it sparingly if having a bad night... then it vanished without a trace. @bingbabe is denying binning it.
We have ghosts here who don't like expired medicines..
I still have some! Not a lot and it is so old that I have hesitated in using it and have been using the old and duff omeprazole instead. Why couldn't they have come up with something just as good!
