I took 20 mg of prozac for about 2 1/2 weeks for mild anxiety issues. A few days after taking it I experienced extrememe nausea, absolute lack of appetite, fatigue, and increased anxiety. I knew that these were typical side effects of this drug and stuck it out for a while, and then stopped the drug after 2 1/2 weeks as they were intolerable. I felt miserable and much worse than I did before starting the drug. It has been 20 days since I stopped taking the drug, but I am still feeling some of all of the side effects. Things have improved a little bit but it has been very slow going. My appetite is slowly coming back, but I am still much more anxious, nauseous, and tired than I was before starting the drug. My question is, when should I expect these symptoms to go away and to feel like I did before starting this medication? I just don't feel like myself at all and am beginning to feel like I will never feel the same again. Am I going crazy or can this happen due to Prozac's long half life?
