So I am on day 9 of taking fluoxetine. I feel like I am getting every side effect in the book. When I first started taking it I could not sleep at all I was getting maybe 4 hours per day and it was from like 7 in the morning to 11 am. I would try to go to bed at night but just lay there for hours. Now for the last few days all I have been doing is sleeping. I would say In the neighborhood of 18 hours a day. My energy is so gone that I have had a hard time getting out of bed at all. I am taking 20 mg and totally second guessing whether this is the right direction for me. I have read a lot that says that the side effects go away and it can take up to 6 weeks to become effective. As soon as I take it I get diarrhea and there goes any of the food it had I'm loosing weight probably around 10 pounds so far. Again just reaching out to if this is common. I just do not react good to certain medications like things for cold and flu. I am wondering if my body is just rejecting this stuff.
