I don't currently have a primary care doctor and I'm not entirely confident in the Nurse Practitioner who is acting as a psychiatrist at my therapy office. He wants me to try a low dose of Lithium, 150 3x a day. My partner feeaked out because they used to require regular blood testing for lithium. I was not given any indicator to get testing. Should I find a second opinion or demand tests? He said this dose isn't as risky as they used to use, but I'm really out of touch on this drug. I don't even know if I'll find a second opinion in the next 6 months, it took me that long to get this guy. I have not started the lithium, till I get a better grasp of the risk.
