I am 40yr ,on 10mg propranolol and 600mg od lithium(at night, 400mg xl and half cut of it), have to wake a 4 to 5 times at night for urine. I am unable to take my sleep properly. what to do, ........... change the dose/strength of lithium, or switch to other bpd medicine or add other medicine for polyuria. I am least interested in adding any medicine. I worry a lot about kidney damage with lithium also. my s. lithium is between 0.4 to 0.8 always.however my s creatinine is below 1.  can anyone share the kidney toxicity data with lithium. Also many a times when I sweat a lot, it makes me tired, only ors than helps me. Happy to get answers from you doctors. do not want to google.
