I was put on lithium while hospitalized, where my blood
could be drawn each morning, and the dosages were increased accordingly until we reached the <span style = 'background-color: #dae8f4'>therapeutic</span> level
. This took a few days, but in an outpatient setting, this titrating timeframe might be extended longer because you won't be getting daily blood
testing. My eventual dose was 900mg, and that was pretty effective in keeping my mood swings in check, or at least in dampening them down.
