I was on it and it worked well. Just annoying side effects of thirst and hand tremors. My husband was on it and went deathly toxic (and he was taking it as prescribed and was being monitored for blood levels). His kidneys started failing, he ended up on dialysis and in the ICU for a week, psychotic because the dialysis pulled all his meds off his system abruptly. Nearly died. After that experience, I absolutely refuse to ever take it again. Just too dangerous. Absolutely traumatic experience.
