Doctors sometimes need to try a few mixtures and doses before they get the meds right. They are tying to get most benefit with least harm.
In the meantime, be frank with your doctor about cannabis and anything else you take. It matters.

Sorry to say, mood stabilizers prevent mania but also keep your mood slightly low. It is a worthwhile trade-off when you consider what can happen when someone's manic.
