Consult Your Psychiatrist Promptly: Inform your doctor about the severity of this symptom. They may consider consolidating your dose to a single nighttime schedule, adjusting the timing, or checking your lithium levels. Monitor Fluid Intake Timing: Stay well-hydrated throughout the day to avoid dehydration, but try to limit heavy fluid consumption in the late evening or right before going to bed. Get a Baseline Kidney Function Test: Ensure your doctor checks your renal profile, including serum creatinine, blood urea nitrogen (BUN), and urine specific gravity, to track your baseline kidney function.

Do not abruptly stop taking your Lithium Carbonate 400 SR or lower your dose on your own. Sudden discontinuation can rapidly trigger a relapse of manic or depressive bipolar episodes. Do Not Restrict Fluids Excessively: While shifting your fluid intake away from bedtime is helpful, do not severely restrict your overall water intake during the day. Dehydration can cause lithium levels in your blood to spike dangerously, increasing the risk of toxicity.
