Hello, my doctor just put me on 150mg Wellbutrin once a day to help with my panic disorder and anxiety. How long does this stuff take to work? My mind is racing and I am having to take more xanax than I normally did. I am only on week one right now and I am hoping that this medication can get me off of xanax and get me feeling like my old self. These panic attacks came out of no where! Any advice would be great! It just sucks that I'm going through this crap while having kids and nothing to really panic about...
