Hi Country girl,
Sorry you are still feeling anxious (blooming horrible side effect). Dont be afraid to take more diazepam if you need to...you wont become addicted, it will help you whilst you are suffering the side effects, even if you need to take 2mg 3 times a day you will soon wean down once the side effects disappear.
I felt like you and was scared to take them but found that I just needed that extra help and as soon as the citalopram kicks in you wont need them as that will help control the anxiety and panic. I tended to take 2mg in the morning and 2mg at lunch time as I felt at my best in the evenings.
I hope the effects soon pass hun and you start to feel better. After about 2 weeks hopefully you should start to notice a difference...I did anyhow.
Take care
Jo.xx
