Citalopram
"Posted nearly a year ago about how I was going which was good at the time. Having been on them for 12 months I thought I could do an update. Has been really good for me. I suffer all the severe physical symptoms that come with anxiety and citalopram keeps them in check. I do notice if I forget to take my dose (20mg) for more then 2-3 days my anxiety flares up again. I still have the occasional off day but its never been anywhere near my pre medication days. Happy with the low dose. I really recommend exercise and eating well if you suffer anxiety. 
You can't make a judgement on only a weeks worth or less of taking this drug. I see lots of people posting 1 star after a day on it. You need at least 4-6 weeks to see changes."
