You might want to ask about this on the bipolar forum. Several regular posters have managed their symptoms without standard psych meds and will have helpful information for you.

CBT is a good option for therapy. Personally, I have found best results from a therapist who is more eclectic but has a definite behavioral bent. He is able to more personalize my therapy as he isn't purely a one trick pony. The CBT skills are really effective; just not exclusively. Some purely CBT therapists can't seem to get beyond their worksheets if you know what I mean. A therapist with a strong CBT background but who does not rely entirely on CBT seems to hit more of the whole person.
