... Brintellix 10 weeks ago and it imprived my depression so much in beginning i thought it was a miracle drug. However, I am 10 weeks in and noticed that at week 9, started having severe flu like symptoms like headache, severe nausea, diahrrea every day all day, shakiness, increased anxiety,etc. It was like I fell off a clift. Meds were working so well and then all this started. Has anyone else had this experience??? Really need help with this. Doc wants me to take 5mg every other day to see if I get any relief from side effects. I am also noticing that depression is coming back now. Please, if anyone had similar response several months into this med???
