"i am 22 year old female and taking zoloft for social anxiety. about a day after starting this medication i began clenching my jaw really tight. my jaw starting aching after a couple of days because of the clenching. i had a panic attack on the train 3 days after starting this. i had nausea and a loss of appetite. the medicine did not really ease my symptoms in fact i would get random occurrences where i would feel extremely nervous and find it difficult to breath. my breathing became very shallow. i am weaning myself off it after 40 days on it."
