Do the bursts of energy feel suspiciously like cycling? SNRIs are known for inducing cycling, so I would watch those bursts of energy very closely if I were you. The last thing I'd think about right now is going off the mood stabilizer. It may be doing more than you realize and coming off it now while taking the Cymbalta could send you flying.

Does your pdoc have someone else in the office covering for them? The end of February is a long time to wait to make adjustments. I don't think you're whining. You sound like you're in a lot of distress and have a right to feel well.

I'd try calling your pdoc's office again. You're not bothering them. That's why they're there.
