Two months ago I asked you all for advice on this problem. Thank you again for all the helpful replies.
Happy to report (touch wood) that while not 100% gone, I am feeling much more sanguine. No more chocolate later than after lunch, and then only a little high grade dark choc. Only one caffeinated drink a day, also no later than lunch time. Try to eat more slowly and chew more (difficult after a lifetime of bolting my food).I haven't needed Omeprazole for a month now (fingers crossed again). Alcohol still on the menu tho not every day! I think chocolate abstinence is the clincher.
Sunny morning today - 0h good. Best wishes to all.
