I am sorry to hear about these concerns.

Some vets offer a free examination to new clients, so call around, and that may save some money.
Here are some other links to possible financial assistance:

The symptoms are not very specific for any underlying pathology. I would be most suspicious for organ issues (kidney, liver, etc...)
Stomach or intestinal upset is another thought.
To help settle the stomach you could try one of the following drugs. My favorite product is Pepcid (an over-the-counter antacid).
Pepcid (Pepcid A.C.)
Pepcid comes in 10mg or 20mg tablets. You can give it every 12 hours.
The dose can be found within the following link:
