I thought I'd update what's going on with Andy. I'm cautiously optimistic - he has not vomited once this past week. I've been giving him a small meal just before bedtime, and it seems to have helped with the excess acid and vomiting in the morning. I did get Pepcid AC and an ok to use it from my vet, but so far I haven't. I'd like to keep him on a reduced drug regimen due to his liver function if possible. I've also been feeding him smaller meals more often during the day. So far he's been his usual self and still has a great appetite. I hope this will continue and I'll adjust his feeding schedule accordingly, even when we are travelling.
