Biaxin and ulcers

I had a really bad bleeding ulcer on 06-02-04 and was in the hospital 4 days. One month later I had to see a GI doctor. He told me that I had the bacteria that causes ulcers. I was given a Prevpac that consist of Previcid 60mg 2x a day, Amoxicillin 1000mg 2x a day, and Biaxin 500mg 2x a day. By the second dose I was nervous, sweating, panicking, and a taste like metal in my mouth. I told the doctor about it and he said I was just under a lot of stress. He said to keep taking the meds. Two days later I had the first panic attack of my life. As the days past the symptoms got worse and I got blisters on my tounge. I changed doctors and was told by 2 different ones that the Biaxin was the culprit. That was 16 months ago and I still have a metalic taste once in a while, nervous tremors, blisters on my tounge about once a month, depression once in a while,and i'm scared to try any other meds to help my current symptoms.
