Explanation:

Early signs of lithium toxicity include muscle weakness, tremors, nausea, vomiting, diarrhea, and polyuria. Weight - gain is not an early sign of lithium toxicity. Blurred vision can occur but is not an early indicator compared to muscle weakness. Oliguria (decreased urine output) is not an early sign; in fact, polyuria is more common early on. Muscle weakness is one of the early manifestations.

Muscle weakness
