You are definitely not alone! I have been on this medication since Feb. 2013, and I have been irritable and short tempered ever since. When I first got on this medication, I wanted off immediately because it caused me a roller coaster of emotions that were not normal for me, such as crying and suicidal thoughts, but my therapist urged me to give it more time. Eventually I stopped having the suicidal thoughts and crying spells, but I am constantly grouchy and very short tempered with anyone who pisses me off (which is just about everyone). I am on the max allowable dose, still depressed, and can't stand how bitchy I am all the time. I spoke with my therapist earlier today, about the irritability I am experiencing, and he thinks it's just life, but I personally think this medication isn't working for me the way it's meant to work for depression. If it's going to work for you, I think you'll know within the first month.
