I used to drink a huge quantity of
diet caffeine free
soda on a daily basis. I quit 3 weeks ago and since then, have had bubbles in my urine. Also, there seems to be a film on the top as well. The bubbles disappear after a few minutes but I still get them. I had a negative culture and urinalysis and am really concerned. My sis has kidney disease and one of the things the doc told her was "you noticed the bubbles in your urine, right?
