The danger with lithium is that too much over extended periods can cause closure of
the tiny arteries in the kidneys, and there's nothing nephrologists can do about that.

I know because I had damage from it.

I do think it's best to set a routine, even put all your pills in a cabinet and set a
schedule for A.M. and P.M. (before brushing teeth in A.M. and after brushing teeth
for bedtime. That's the easiest way to remember to take them on schedule.)

Hope you're feeling better soon.
