I've had full-blown manic episodes when on an AD alone, but am fine now taking Zoloft in conjunction with an antipsychotic (perphenazine). I can definitely see how ADs could cause this kind of side effect, though, especially initially. My thoughts are with you, and I hope the ultra rapid cycling eventually evens out so that you can enjoy the effects of the AD without all of the mood swings!

All the Best,
Hope
