I take 1125 mg of Lithium. The dose does not matter, but the blood lithium level matters. Most p-docs try and keep blood levels below 1.2. My blood lithium level is 1.0.

The p-doc chooses the dose based on weight, height, gender, etc. The blood levels should be checked frequently in the beginning, like weekly or every other week. Later, every 6 months is fine.

If the blood lithium levels get too high, you can get lithium toxicity. Symptoms include passing out, feeling nasuea, dizzy, headaches, stomaches and tiredness. Watch for these.
