I know, with all of us it's rarely--rarely ever situational. Wellbutrin caused me anxiety. It's an upper for it raises dopamine and norepinephrine. Excess norepinephrine may trigger anxiety. It may also cause you to wake up at night and insomnia. It did with me. It did nothing positive for me and my roommate, which is odd, I expected it to help my roommate stay awake since she has mild narcolepsy. Raising the Wellbutrin won't take away your anxiety from what I've read and experienced.

Also they say that 400mgs of caffeine a day is okay. I know if I have more I start to shake and can't sleep. I try to stay away from it in the evening. But this is just minor stuff to tinker with that I consider when I consider when my meds are working comfortably.

Maybe you're right and you've built a tolerance to Paxil or it's just not with your unique brain chemistry. There's many recommendations I have but I don't want to say them because I don't want what happened to me to happen to you...
