Not necessarily bad.
I was on 600mg of lith and 200 of lamictal.
She said that after roughly 8 years on lithium, it could lead to side effects (thyroid and kidney) as well as the amount I was on was probably not doing much anymore (I did need my meds tweaked).

She put me on 100mg bid of the lamictal instead of 200 at once. I was feeling myself crashing and getting lethargic about 6 hours after my lamictal. New dose seems to be nice.

Anything I should watch out for getting off lithium?

She also prescribed Trazadone for sleep (50mg) because I have some issues with that. I can use it prn, and I'm not a fan because it's an antidepressant and those have sexual side effects I am prone to, mainly libido.

Anyhow, thanks in advance for any advice.
