Went to the vet. He prescribed two meds; one for the morning and one for the evening. He also gave us some bland canned and dry food. He takes the meds for 4-5 days. The canned food is more to hide the meds into.
Vet said if he continues to vomit while on meds and bland diet then we will do xrays and bloodwork.
He took meds and ate food last night and this morning and so far all is well.
