"never taken antidepressants before my therapist encouraged me to try them. her and the doc both suggested celexa and 20 mg to start. doc said i would probably experience headaches and nausea. within 20 minutes of taking my first dose i had an extreme skull crushing headache and suddenly felt so tired (i had just woken up so i wasn&rsquo;t) i laid down and felt stiff and unable to move. i felt so dizzy laying down and drugged. 2 hours later i was hit with trembling, hot flashes, vomiting , diarrhea, dizziness, confusion, seeing dark spots, slurred speech, pounding heart and trouble taking deep breathes. i felt like i was dying and almost called 911 because i couldn&rsquo;t do anything to lessen the symptoms. it gave me serotonin syndrome. never again."
