The thing with Citalopram is that its a jog not a sprint - its different for everyone but you will get a bit of a rollercoaster for a couple of weeks. I have been on them 27 days now and while I get some strange side effects for a few hours after taking them they are managable and the original symptoms are disappearing. Everything I have been told on here indicates that you will only start feeling the full effects between 4 & 6 weeks. Don't be frightened by the weird side effects, thats quite normal, its just your body adjusting, try and drive through them if you can.
