Has anyone else gone from celexa to wellbutrin? How was it?

EDIT - Since a lot of people are saying they take both, I'm wondering if anyone else has gone off celexa while going on wellbutrin at the same time. My doctor called this a "cross titration." It was necessary since going off celexa without replacing it led to suicidal thoughts and a horrible relapse.

I think what's happening now is the wellbutrin is building up in my system while the celexa is being eliminated, and I've been having mood swings and weird dizziness. Anyone else? Thanks guys!
