I was prescribed 75 mg of Wellbutrin for anxiety & depression .since I am such a slow metabolizer I cut the pill in half for the first five days now I'm taking the 3/4 of the 75mg pill. It's seven days now & I'm experiencing a fuzzy & heavy head feeling..also slight dizziness... is this normal to feel like this only into this a week. I've tried celexa & Lexapro the side effects of those were a feeling my throat was closing & constant tiredness ... my anxiety is so bad I went to the ER 2 Sundays ago ... I am really hoping this one works ..anyone have those feelings in their head ??
