I'm on prozac and I've been taking it for about 5 months now. I've had a variety of side-effects which have not been too serious (in my opinion at least.) Basically I've always had problems sleeping but I've been getting lots more sleep than I'm used to. And nightly. But for some reason I feel more tired during the day than when I couldn't sleep at night at all. I always feel like I need to crash by about 4pm but I don't so that I can sleep at night. This is just getting on my nerves now. I know I should ask the doc but if I have anymore side effects they're thinking of changing the meds to something else and I don't want them to. Any advice or anything at all would be helpfull.
