Fluvoxamine
"After 10 years of struggling with heightening anxiety, I came very close to breaking point, and checked myself into a wonderful private psych hospital - which at the time, I found absolutely terrifying. Little did I know, my timing was perfect, as I met my new doctor (an angel/psychiatrist) who made an OCD diagnosis straight away. With him, I started on 100mg of Luvox, which had a positive effect within 2 days. We increased my dose to 200mg per night, which has continued to work superbly ever since (and it's been 1.5 years). I can't speak highly enough of Luvox, which is the one and only medication I've tried. The biggest thing I've learnt about OCD, is that the 'cure' (aka, return to the healthy pool) = medication + psychology + lifestyle!"
