So I was on lithium for a year and a half, and my level came back toxic last month. I'm not sure how long I was toxic for. When they discovered I was toxic, I was sent to the ER to get an IV. After that, I got blood taken every day for a week, testing for different things like lithium level, electrolytes, and kidney function.

Around this time I started to notice differences like I was thirsty all the time, and was urinating large quantities of dilute urine. The blood labs indicated there was a problem with my kidney function, and the urine test indicated my kidneys weren't concentrating my urine.

Since then, it seems to be hit and miss. Most of the time it's the same, extreme thirst, large volume of dilute urine. But maybe once or twice a day, I'll pee and it's totally normal looking.

In addition, I feel sick. Nausea, dizziness, fatigue. I thought it was an electrolyte imbalance but I got that checked today and my electrolytes are fine.

I did a 24 hour urine test, finished that this morning, and the volume was much greater than normal (7 L in 24 hours) but my psychiatrist says the tests all came back normal.

It's frustrating to feel so worn down, I'm not sleeping at night because I'm peeing every hour, but the labs don't indicate a problem. My psychiatrist is referring me to a nephrologist, and I'm also going to talk to my endocrinologist.

Am I being a hypochondriac?
