that majorly sucks....

without my lithium I get really depressed and suicidal within a couple of weeks, don't really notice it at first.

stopping lithium suddenly is really bad as you can become resistant to lithium when you restart (i think that only happens if you have a rebound mania after stopping) so if you ever run out again, try to taper even if it is only for a few days. but sounds like you are ok at the moment. hang in there.
