what drug can i take instead of lithium .
I really appreciate you visiting my site and reaching out. However, I can not answer your question. I respectfully need to refer you to your psychiatrist or family physician that understands your diagnosis, your current medication treatments, etc.
It is important to know how each of your medications would react to each other, the side effects, etc.
I am sorry I can't answer your question but hope to help you by encouraging you to seek out qualified advice / treatment plans from the medical experts who you currently work with.
Wishing you all the best,
