What time of day is it that he usually vomits?
How often is he being fed?
What type of food does he eat now?
Has your vet ever tried medications?

I understand what your vet is trying to treat and by spreading out the meals this should help but if the first and second meals aren't early enough or late enough then it is all for not. Some dogs develop a sick tummy the longer they go without food. Her time span is limited here more than others so what she may benefit from at least for a short trial is an antacid. If you are up for it I would like for you to try 1/4 pepcid twice daily. Once in the AM and once in the PM for three days then you can decrease this to 1/4 pepcid once daily in the early evening. When we increase the number of meals we are trying to avoid the build up of acids in the stomach when the stomach is empty which leads to nausea and then vomiting of bile. With the pepcid we are just going to neutralize the acids and avoid all the work of figuring out timing.
Are you willing to give this a try?
Also, you mention an enlarged adrenal I would suggest having an ACTH stim test performed to rule out Cushing's disease as this can affect the liver and even cause stomach upset because there is an overproduction of Cortisol. If you haven't had this test performed I would consider it. It may be a longshot so early in the game but based on some of her symptoms I would have it done.
Please let me know what you think.
