Keep in mind that the combo that works for one, may not work for another. The key to the medications in the msg you replied to is Lithium, the mood stabilizer. The Effexor, I believe, is to assist with depression.

And if you experience mania while on Effexor, your doctor may have taken you off Effexor for that reason. I only say this as a possibility because I, for example, become manic when taking anti-depressants. Especially the same anti-depressant that I took for 6 years in my late teens, early 20s (odd how it never used to make me manic until now)

Anyway, like someone else said, have patience. If one medication doesn't work, try another. If you run out of medications to try, look into other practices. Keep in mind medications may not make you feel 100% how you did before the bipolar onset. DBT (dialectical behavior therapy).
I think I've gone off topic here. Just some thoughts to help.
