I have tried so many SSRI's with no luck and horrible side effects. My psychiatrist started me on mirtazapine. 15mg first week and 30mg second week. I am on day 15. I take this at night. First week I was super tired and had extreme dizziness. Then followed with intense headaches. Those have subsided. I slightly feel them still but definitely not as bad. My anxiety was triggered from surgery I had in April. It is now September and I'm still not getting any relief of the anxiety. I can't leave my house. I can't go to school. I can't take my children anywhere. I'm hoping that this medication helps! Any success stories and time frame is greatly appreciated!
