depression
"I am 25 year old PhD student. I have been taking Prozac for 5 weeks now. It started affecting me on the 3rd week. I felt so much more active and I had hope for living. I am working more efficiently and my sleep schedule is perfect. I am gaining some weight which means I should also start exercising. I still have vivid dreams and wake up several times during the night but I don't mind it because my life has changed so much and I feel so happy after years of depression."
