re in Paxil withdrawal and, because you started another drug at the same time that has a completely different mechanism of action, you have the side effects of starting another drug that may not even be an appropriate substitute for
Paxil. What you should
do is, if you just started the wellbutrin, stop it,
go back on the Paxil, and taper off slowly, as slowly as it takes because you aren't anyone else. What you have are classic Paxil withdrawal symptoms.
