Depression
"I was on Zoloft years 9 years ago for social anxiety and it worked great for me. I decided to get off it but slowly all my symptoms came back. Also got very depressed. Got back in Zoloft 7 months ago and I feel great again. I did have to get a night guard from my dentist. I chipped two from teeth and cracked a molar from grinding my teeth. 200mg daily."
