Thanks everyone for your replies.
CKLD - you have a good point, perhaps I am hungry? I try not to eat much in the daytime because of HA issues (scared of needing to find toilets - that's a whole other story) but thinking about it I don't get as much gurgling in evening when stomach is fuller or maybe I am relaxed then (and have had a glass of wine).
Tiggergirl I think its called borborygmus. Just looked it up. I did have a very brief look on Google, but I can't stay there long when the pancreatic cancer sites start coming up. The general gist I got was that gurgling is normal and lack of gurgling is a bad sign. Seems a common problem although most people were complaining of pain/ discomfort with it, which I don't have just wind. It also seems to be always on the left side.
I will try to keep a food diary. Following the antibiotic episode I did increase my activia intake to three a day - usually I have two. I can't get Yakult or Actimel here (France). Last year I was getting more IBS/d type issues especially in the morning after breakfast, so I stopped eating museli/ milk and eat these sort of breakfast biscuit things, but they are still wheat based. Not sure what else I could eat for breakfast. I suppose my diet is a bit weird - I'm mostly vegetarian although we will have fish once a week/fortnight and I don't eat any cheese except goat cheese (OH intolerant to cheese), don't drink any milk or tea, don't eat much fresh bread - more toasty type stuff, 'cos I felt that the fresh bread was too yeasty, usually have a boiled egg for lunch. It's difficult to work out what it could be - coffee perhaps? only have two cups in the morning, too many activias?
On balance I think it is probably related to the HA issue and that is something that I am struggling to control, like so many of us
