Helo everyone. I take 1125 mg lithium extended and have blood levels of 0.43 so. How can I push these levels? Only by upping my dose? Is the minimum level really 0.6 for any success? My doctor's says everything above 0.4 is good. What's the max dose? Let's say e.g. are there any problems to take 5000mg maybe for reaching 0.8, if it doesn't exceed the 1.2? Or would that have side effects on the kidney for sure? Never had any problems with this. Only the effect of gaining levels is hard to get. Thanks for answering
