I started taking the starter pack of Viibryd about 3-4 weeks ago. I'm currently on 20mg, however I've been cutting the 40mg in half by advisement from my dr. Since cutting it in half, I've been having diarrhea almost every time I eat food. The med doesn't seem to be working as well as when I first started. I have no motivation, feel numb, but not sad like before and can't seem to be productive in my personal and work life. Going to the dr today to see if I should increase to 40mg. Was wondering if anyone had any insight on this issue. I also take Ritalin 60mg a day. Thanks!
