Hi I've been prescribed lithium for adult ADHD and bipolar 2 since begin on it things have been fine but I have suffered cystitis for the past month has any 1 else suffered this on lithium is this 1 over the side effects of lithium or is this unrelated? Can any 1 given me some insight please I'm at the end of my tether, every thing else is fine no weight gain, tremors, headaches etc
