I have had a lot of meds change in the last few months due to side effects. I am having severe anxiety, panic attacks, irritability, crying spell. I started Prozac 20 mg about 12 days ago. I am having some weird sensation that I have a hard time to describe. I dont know if its dizziness or lightheaded but I dont feel myself. Sometimes nausea, fatigue. I still have to rely on clonazepam more than I like. I'm hoping it will get better. I will talk to my psychiatrist tomorrow.
