I had a doctor like that too. Just because the lithium levels were fine, he wouldn't switch my meds. I think its very unprofessional for a doctor to not listen!
Just because levels are fine doesn't mean our kidneys can't get damaged or our thyroid won't suffer. You don't have to be sick and stable. Healthy and stable is an option, and you deserve that option.
I've heard very good things about Lamictal. Don't worry about sleepiness, you can take it at night, and if not, then remember that the sleepiness isn't permanent. It will go away once your body gets used to it.
