Welbutrin

Sherman had a welbutrin today. I dropped it when I was loading my little pill holder. The pills are so tiny, SOOO tiny that I can barely hold them in my large size hands.
I wasn't sure he had eaten it, I had dropped it. I got down on the floor as much as this hurts me, and looked for it eye level. I couldn't find it, I thought maybe I had dropped it in the sink, they desolve fast in water. I HOPED.
a few moments later I heard Sherman throwing up. I ran into the bedroom to check on him. It was just stomach bile, so it looked, but it occurred to me that it was probably the pill and he would probably be fine. I looked it up online, all I could find is that a welbutrin pill wont hurt a dog, I don't see how that could be as they could hurt a human.
He hasn't seemed any different to me. IF I had any money I would have run him to the vet, but our vets wont see a dog without cash in hand. I guess I don't blame them, but if I ever have an emergency, my dog is dead and I dread that. I love my dog, why should only the wealthy be able to have pets? DAMMIT.
I am hoping that there will be no life threatening effects later. He is eating and drinking like normal. I know I worry, but I don't want to lose him.
