50mg for 2 months and exactly 2 months today on 100mg. the only side effect i now have is a pulsating feeling in my lover jaw/gums. back of head and also in my chest area. its as if my body is pulsing to my heart beat. this is someting i also had before meds so i would say that the sertraline has maybe heightened this. if i could get rid of these symptoms i would be laughing. on a positive note the tablets are working. i would urge people to stick at sertraline. it will get better.
