I have been on 20mg fluoxetine now for 4 days and the last 2 days when i have woke up I have started getting tremours and shakes in my body and feeling extremly tired after only being awake a few hours. My vision is also very strange. I am blind at the best of time, but is this normal for vision to go bit blurred. I would appreciate any comments back off more help and understanding about this medication, as my doctor was useless and just rushed me into deciding to take them, because it was only a ten minute appointment. Please any information would be so helpfull to me.
