Hi Ljt
I am on 200mg of sertraline a day, I find it very good at quenching anxiety. There are med that works straight away for anxiety, sleep etc.. such as xanax, valium, ativan, klonopin but they are addictive so you might not want to go down that road or your doctor might not want to but I am on valium along with other meds and they work great for me. Perhaps ask the doctor if there is something you can take until the sertaline takes effect?
