I have not been on here for a while, but truth be told I am so tired that I just want to sleep all the time. I had a bad spell of depression and was prescribed Prozac. I have been taking it faithfully for almost 3 months now, 20mg a day. Trouble is I just feel like a zombie now. Mood has improved but I just want to sleep all day long. Do you think that this is a side effect of the drug? I am going to make an apt. with my doc but is there a smaller dose do you think that I can take?
