"i have been on brintellix for 6 months. started on 10mg. initially like everyone else thought it was great with the exception of nausea. it also helped with the quality of my sleep. after about a month it plataued so i went up to 20 mg but it made me extremely tired so i went back down to 10 mg. 5 months into taking this ridiculously expensive drug i felt my personality is completely changing and not for the better.  i became quick to anger, on the verge of tears, (not typical for me), with an explosive and unpredictable personality.  if that was not enough i was also very tired all the time. the personality changes cost me my job and at home well, it hurt people that i love.  going off of it i was in pain and tears for days..."
