I suggest that you purchase Tagamet (100 mg) tablets. You can give 1/4 of the tablet. He can take this every 6 to 8 hours when the problem flares up. This will help with the acid and nausea.
You can also use hairball medicine that you can find at the pet store. This helps to coat the esophagus and helps with the reflux.
You also need to think about changing the diet to a bland food when this is going on. You can use baby food (chicken/rice, etc) Just be sure that it does not have onion or garlic.
If it continues, you should see the vet.
Let me know if you still have questions.
Lengthening the time between feedings will not help. This will cause even more stomach acid to build up and will worsen the problem. I suggest that you offer several small, bland meals each day. Try not to let the stomach empty at any time. Jarred baby food works great and you can be creative with it. There are some great lamb and rice, chicken and rice and beef with rice foods out there. Just be sure that there are no onions or garlic in the recipe.
I think that you will see significant relief after you follow this path for a few days.
If you don't, you will need to return to the vet.
