Hi. I take wellbutrin and I am also trying to project. I have not really had a conscious projection yet but some interesting experiences (like falling out of my body but couldnt see, but I felt like i rolled onto the floor).
This is just my opinion, but I think that you
can still project while on an antidepressant. It just depends where your thoughts are and how you control them. It may make it a little harder (or in my case i think it may be easier since i can relax easier). I don't know what you can do to get there but I would keep trying.
I think it just depends on where your thoughts are. Make sure they are away from your body when you are trying to project.
good luck!
