depression
"I am 51and female. I have been on sertraline for 3 months and I love it.  I have not had or needed an alcoholic drink since I started on this med. I never thought I could give up my multiple glasses of red wine every night but, after taking a pill, I feel good for 24 hours at a time now instead of just for a few hours while drinking...and without the hangover or expense! 
Also, my Blood pressure and pulse are MUCH LOWER now; My body no longer aches all over; I'm not so nervous, agitated or angry anymore.  I no longer constantly think about death. I am satisfied with my job now, too, and no longer desire to quit.  I'm also beginning to like myself.
Side effects for me have mainly been: lack of appetite, some weight loss, and boring dreams."
