I hope that you get the medication you need.
Regarding the smoking:
I have heard that nicotine helps a lot, just give it a go and see how you can on. However I must warn you that some people get addicted to it.
My grandad used to smoke and after suffering from an heart attack he suddenly stopped smoking and he's not touched a cigarette for years now.
It take's a lot of effort to give in smoking and it will take a long time, so please be patient!
Hope this helps
Pain free hugs

P.S: Think about the damage that smoking is doing to you, I am sure that this will help to stop.
