My moods are playing on the swing sets again

Bipolar disorder II now becomes BD I with rapid cycling "mixed episodes". Moods change variably throughout the day and one day all moods, feelings, emotions come together to have a party in your brain without your consent and you have a meltdown.... Plan A... increase Seroquel XR 400mg to XR 600mg. If this does not work Plan B is to add an additional 100mg dose of lamictal in the afternoon, increasing my lamictal from 300mg to 400mg.... OR Place C.... If all else fails we will try and new antidepressant.
