... they boosted it to 20 which was way too much. I hated the weight gain and wanted to go off so I cut it in half and took 5mg in morning and 5mg at night for about 4 days and then went on Wilbutrin. I feel like I have the flu - bad headache and very nauseau but it doesn't come on til later in afternoon but I seem to feel like myself on Wilbutrin. Is there anyone else that experienced the same thing?
