I came off of 40mg Latuda and was put on 2mg of Abilify. That was 4 weeks ago. I just called my Psychiatrist and she increased my Abilify to 4mg. How long will it take to notice any improvement? I am trapped in this depression and I am starting to ask myself, "what is the reason for living?" I need to figure this out. I am also on 1200mg of Lithium and 100mg of Seroquel (for sleep). PLEASE, ANY ADVICE IS APPRECIATED!
