bipolar disorde
"Lithium did well for me for more than 15 years, but then the creatinine levels went up and I had to switch. Eight years later now, I have hyperparathyroid symptoms, at least that is what it looks like. That is a long time after stopping it to see elevated calcium levels, etc.  But I have no regrets. The last 30 years have been stable. Depakote keeps me well. Just be aware that this could happen."
