I have been on this for anxiety for since Aug. 20th. I have lost about 20 lbs. Little appetite. Which is ok. But the other side effects are headache in the morning, period every two weeks and tiredness. Is this normal? And will it get better with more time on Zoloft?

I currently take 50mg of zoloft daily. I've been on it since august 24th and I haven't noticed a loss of appetite or weight. When I was on Prozac back in march I did have a loss of appetite though, that soon went away within about 6 weeks. With zoloft I have been having mild headaches every now and then, but that may be because I don't drink enough water. I can't say much about your period symptoms because I'm on birthcontrol and get my period exactly every 4 weeks. When I told my mom I switched to zoloft, she said it would make me tired ( she's been on zoloft before ). I haven't noticed being tired, but that's just me. I'm pretty sure all of your symptoms are normal except for the period every 2 weeks. As your body gets used to the medication, your symptoms will go away.
