"unfortunately this medication did not work out well for me at all. i was on 150mg of wellbutrin a generic sr version. in the first week i took the medicine first thing in the morning as directed (for me that&#039;s about 7a.m.), and the rest of the day i had intense/severe headaches. mind you, i already take medication daily for migraines because i&#039;m a chronic sufferer, and my migraine medication was being blown out of the water! i felt like i had several ice picks in my head. the other issue i noticed immediately was that i was having an extremely difficult time sleeping and if i did fall asleep i&#039;d have very vivid and awful nightmares. other apparently issues were having memory loss and abnormal behavior. not for me!!!"
