This is my 3rd day on this Fetzima and I think it is horrible! My head feels like it is going to bust from headache non stop, I've been sick to my stomach, throwing up, I am very irritable, jaw is hurting, ever bone hurts BAD! I have chronic pain and this is horrible! Does it suppose to reverse after so long or what's the deal with this stuff? I think I would rather be depressed than deal with this pain that is disabling me more. Help
