I have no reason to doubt what my vet said. She was, like me, very surprised at the reflux, but as this cleared the problem with the anesthetics, I'm just glad whatever happened did (real vomit or not) so I could get my piggy back.
As for drugs, again, i'll follow the professional advice I'll be given. As a professional, I hate people telling me how to do my job when they clearly haven't got a clue. Ibuprofen is a great drug, very effective, but there must be a reason why pregnant woman and asthmatics can't take it. So I just won't risk it.
Anyway, thanks for all the advice, but at the end of the day, I'll be making the decision of what goes down my bertie's neck.
