I used to take Prozac years ago and don't remember any side effects. Been prescribed them again as i was feeling Stressy about side effects I took it about 11 pm last night before bed been fine all day until now I've sat down with a coffee and can't hardly keep my eyes open not sure if it's to do with the Prozac or not. When is the best time to take it. Feel absolutely exhausted and typical I have an open evening and dd school tonight
