Also for extreme anxiety. It worked very well for me in the past but now I've just started it again 20mg... I've tried many other SSRI's to no avail also so that's why I'm going back after 2 years. However I'm only on day 2 and my anxiety is FAR worse..I can't sleep at all either. Will this subside?! Someone give me hope as I mentally cannot do another med switch!?
