Im on litium too evildouble....I dont understand why your levels are always out.My pdoc says levels(or at least mine) should be around .75....presently my last level was .50...so I was bumped up.
I started on regular lithium carbonate now Im on Duralith which is MUCH better.Taken only once a day.
Ask your pdoc if thats an option.....I really like it compared to other meds Ive been on.
In the meantime stay safe....
