Everywhere I've read says to take it in the morning but I am on 20mg of Fluoxetine and take it every morning around 10.00am. I then spend the rest of the day in a completely tired haze and could quite easily sleep all day but then I spend the night waking up all night. I was wondering as I'm so tired during the day could I not take it at night as then I would hopefully be able to sleep which I'm not doing well at the moment.
