Teasals gas - on and off - still worried

OK so on Friday he had gas (and no indication of blockage o blockage like back up of material etc on an x-ray). The vet gave Buscopan and pain killer - we rubbed tummy etc and it gurgled and he got better like magic.

By late Friday eve and all day Saturday he looked great and looked just like normal. Vet moved him onto metaclopramide to make sure gut got back to normal after the gas attack and he has been having it twice a day.

Today (Sunday) in the morning he looked a bit gassy again (sort of swollen a bit and sits oddly and stretches a bit),
so I bought some Infacol and at c1pm gave 1ml Infacol (he weighs 2k approx); he seemed a bit better, and was eating hay and pooing etc;

Now (Sunday at at 7pm) he looks gasy again. I have given another 1ml of Infacol and tummy rubs (he HATES them).

I have never given Infacol before so am a bit worried about it - it seems very sugary. My vet would probably kill me if she knew I was giving him non prescribed baby stuff.

He NEVER has gas usually. But I am really worried about this as it seems to just come and go.

Just as I think he's over it it seems to come again just an hour or so later.

Any ideas what i should do next????

The Infacol wont harm him as long as there is no blockage.
As he appears to be getting recurrent attacks I would want to be looking at exactly what he is eating. Is he passing normal poos ?
Metoclopromide can cause gripey tummy pain. Could it be that is what is now causing his discomfort?

I think what may have first caused it was my (very nice and experienced) bunny sitter feeding him too many greens last weekend - when we were away. It was my fault really as I left huge amounts in the feed buckets - but didn't make it clear that that was the food supply for the whole week week that i had just collected/bought rather than just to be used at the weekend. It included supermarket bought cabbage and brussels as well as the allotment collected weeds/grass etc etc. I think the gas may have developed then and just sat there - we did think he looked a bit 'off' when we got back on Monday but it did not come to a head until Thursday.

However I don't know what is causing it now as since Monday he has been back on normal hay, willow, brambles, apple leaves, a bit of long weedy grass, and a VERY VERY VERY small amount of Oxbow T (about a thimble full).

Its just s scary that it is coming and going . So far its not as bad as Thursday but I am really scared it will get that way.

Do you think I should give some more metacam? he had 3 drops at 2pm. I don't want to skip the metaclopromide dose this evening really in case he needs that too!! How often can I give Infacol? He stuffed loads of hay this afternoon but he's stopped now and is getting very fed up and annoyed at all the hassle as well as the gas..
