I had been on the Lexapro for quite some time, that I felt I was getting immune to it somehow. So, I asked my doctor for something stronger and she (reluctantly) prescribed Prozac. At any rate, I started the Prozac about a week ago taking it, as prescribed, each morning. I wouldn't say I'm sleepy or drowsy, just sorta lazy n not wanting to do anything during the day. Also, have headaches, irritability, depressant symptoms (crying, not getting out of my house, or even checking on my business), and short tempered. Is that normal when first starting the medicine? Should I try it at night or just give my doctor a call? Or is that premature? Please help? Thank God for my husband! He's just doing everything, plus worrying about his own health and me! Thank you for your feedback!
