"i was on zoloft due to depression and anxiety. i am an army veteran who was diagnosed with gad and mild to moderate depression. i have been on a variety of medications, however this one was hell. i couldn&#039;t concentrate, my insomnia was worse (i had to take melatonin in order to sleep), i was lightheaded almost everyday. the one thing i hate was being irritated easily were when it came to my family asking me questions, i just wanted to be violent."
