"taking it since one month because of a reactive depression for over a year. i have never taken anti-depressants before and kept refusing although my psychologist urged me to for several months. when the depression kept getting darker: no energy, sad, bad insomnia and constant thoughts of suicide (which my psychologist didn&#039;t know) i decided to take the advise to start on brintellix (was either that or kill myself). the first 4 days i was so tired i spent most of the time in bed . then i just started to feel better and better. high energy level, creative, not sad, no mood swings, slept great at night and best of all the suicidal thoughts just disappeared . i started and stayed on 5 mg. no side effects at all, working night shift no problem!"
