I just stared Prozac to treat my anxiety. I am on day 2 of 10mg and on day 7 I'm upping to 20mg. So far I've been really drowsy and have had pretty bad headaches. I'm wondering when these side effects will go away/how they'll change over time, especially since I will increase my dosage soon. I've also heard of nausea/loss of appetite and am wondering if I will have that in the coming days. Anyone with experience on Prozac please let me know!
