"i was first put on wellbutrin at 300mg then 450mg but that kept me up and i really wasn&#039;t feeling much of a difference. the doctor added prozac 20mg. for the first 3 days i could sleep. after that if feels like i&#039;m coming off a caffeine high as i get very tired but i never experience a high in energy. i get hot flashes and sweat about 25-30mins after taking it but then it goes away. i yawn all the time. another thing i&#039;ve noticed since i&#039;ve been on it was decreased sexual mood and ejaculation feels weird, just weird. i&#039;m not emotionless but sadness, depression and anger seem to not be present. decreased appetite and lost a little weight. no other side effects experience."
