Should I continue taking my antibiotics?

I went to the doctor because I had a really bad case of acid reflux and also appear to have a vaginal infection. He prescribe antibiotics for the infection and some anti-acid pills, liquid medicine that it says to cure ulcers and another blue pill that helps with irritable stomach.

It's been 3 days and I feel a lot worse. I had to stop the blue pill the first moment I took it because I immediately throw up after like 3 mins of taking it. I've been with diarrhea these 3 days and every time I take the antibiotics I feel soo much acid on my stomach, throat and saliva of what I already have. I have to take the antibiotics for another 3 days but I don't know if I can take it anymore. I already lost 3 pounds and I'm extremely weak and with constant nausea.

I've been eating: chicken soup, papaya, apples, jello, pear nectar and other things to keep me hydrated but doesn't improve how I feel. My questions is: Should I continue with the antibiotics?

I would ask my doctor but I'll have to wait until Monday.
