Lithium (Acute on Chronic) Toxicity

Hi! I (25F and 73kg) have Bipolar Disorder II. I am prescribed to take 2 1/2 tabs of Lithium Carbonate (450mg). Yesterday, I intentionally ingested 20x450mg (9000mg). So far, I vomitted 4x, 4x LBM. I am also experiencing dizziness ans drowsiness. What else are the things that can happen? Update: There is no GI issues already. But, I feel drowsiness, no appetite, and irritable. It has been 31 hours since the ingestion. Thank you.
