"i&#039;ve never taken antidepressants before (i&#039;m 19). back in november i started zoloft at 25 mg for one week. i felt good, my energy was high. but after about 5 of those days, i got bad headaches. then i started my 50 mg dose. i was even more depressed. i stayed in bed all day. i had panic episodes more frequently. i barely ate, i lost close to 10 pounds which really scared me. i couldn&#039;t take care of myself. i thought i was losing myself. then i was told to go back to 25 mg. i felt better, less of a lump, but i was still having depressed feelings. i got off zoloft back in december. consult your doctor before completely cutting off! i hope my dr. will prescribe me something else..."
