I take 300 mg a day split between two doses.

I stuck at 150 for a while it helped but I still had some mood problems, nothing major. It kind of quelled the symptoms but didn't really reduce the frequency of my mood changes at that dose.

In outpatient treatment (for other, non-bipolar mental health stuff) it was increased by 50 mgs. Over a few months last summer the additional 100 was added. It seems to be the perfect dosage for me.

Glad to hear its working for you. It really is a good med.
