I have had bubbles when I urinate for 3 weeks. I have been taking b-12 vitamins at the same time. This has happened before and it went away. I am 62 years old and I am 6 foot 2 and weight 207 pounds. I have never drank, or smoked. I worst habit has been not eating enough fruits a vegetables. I began drinking lots of water daily since 2011, to try to stop drinking too mush soda. I was raised on red meats and have cut back on this consumption.
