"i have been taking prozac for two months.  the first month i did not notice a difference but after 6 weeks i was not obsessing or getting angry and noticed i was more relaxed around other people.  being a shy person from the day i was born, i am still not interested in anymore social interaction, however i have noticed that i am now extremely tired on the prozac which is debilitating and frustrating since i have an exam to write in 10 days and have no motivation to study.  i have lots of energy when i am exercising so i don&#039;t think it&#039;s due to low iron or nutritional deficiencies.  went to doctor today and he recommended i stay on it for another month so the medicine normalizes in my body."
