I was just put on 20 mg of Prozac & take it in the morning because I was told it would keep me up at night. But about an hour after I take it I have to go back to sleep & it makes me so drowsy the rest of the day & when I go to bed I sleep great but when it's time to wake up I have to pull my eyes open with my fingers.. So I've told because I get so sleepy to take it at night.. I'm just not to sure about it because I'm always tired & feel retarded n spacy
