What Can I Do About A Very Acidic Stomach Accompanied

What can I do about a very acidic stomach accompanied by pain that feels like it comes from just south of the breast bone? I have been up two nights now. I have thrown up last night and tonight. I bought some omiprozol but it is not working. I am on night time doses of gabapentin and cyclobenzapren. I appologize for my spelling. Any suggestions?
