I'm reading the comments regarding taking sertraline. I've been prescribed it by my g.p and am so scared to take it. I've been on 10mg citalopram for about 15 years and I don't think they are working any more. Apparently you can get so used to them, they no longer have any effect. My anxiety is so bad right now and I'm really scared of it getting worse before it gets better. I know not everyone gets side effects, but I seriously couldn't cope if it did.
