Biaxin and severe stomach pains

I am a 21/f, 105lbs. I began taking Biaxin XL for what was a bacterial infection in my throat and a mild ear infection. I have been taking 1000mg daily(all at one time as prescribed) for four days(I still have three days left on my prescription). My side effects include: severe stomach pains and discomfort, nausea but can not vomit--until day 4, loss of appetite, metalic taste in my mouth that never goes away, digestive problems, dehydration symptoms, trouble sleeping, extremely moody and emotional. I am unsure if I will finish this prescription, most likely I will not. I decided to check more about this drug tonight after another miserable day. Taking this medicine is worse than my sore throat and ear...I am not sure if taking Biaxin is worth it, the side effects are too extreme and last 24 hours...
