"i&#039;ve was dubious about lithium and didn&#039;t want it. time came that it was a choice left. at first i had nausea, and thirst. my doctor out me on a xr brand and it was better.  i can honestly say today, i don&#039;t know if it&#039;s working or not.  it is such a medicine that just does what it needs to do.  but a warning is- watch your salts either on your plate or in the sun.  i was told by the chemist and then i became aware when one day, i was out in the heat and walking around. i felt faint after a while. next day i felt washed out.  and this has happened a few times.   lithium is based on salts and this can play a little chaos.  especially in the heat."
