Suggest Treatment For Recurrent Bladder Infection

Hi. I have a bladder infection. It is reoccurring after treatment with macrobid for one week. I am Canadian in the US for another few weeks and would like to solve this myself without seeing a doctor for a prescription. What can you suggest? I plan to give up caffeine. I drink wine and soda, a few glasses each evening and now know that the soda is bad (carbonated) and owner about the wine. I am taking cranberry tablets and have just increased my vitamin c. Drinking lots of water, urinating a often I fell the urge. My urine is back to being cloudy and slightly foamy. Anything I am missing in home remedies? Thanks Ginny
