I was on Zoloft for about three years for anxiety and was switched over to Wellbutrin last week. There is a huge difference. Besides the very vivid dreams, I am feeling very lethargic and fuzzy headed most of the time. In addition, today I have started hearing "whispering" in my left ear which is very distracting and disturbing. I'm thinking either my dosage is too high (150 mg twice a day) or I'm having some kind of allergic reaction to the Wellbutrin. Hopefully I'm not going psycho. Any experience or advice is appreciated.
