..."It's easy to quite smoking, I've done it over twenty times"

If you've found that Zyban and Wellbutron worked for you in relieving the anxiety and only the resulting insomnia was a problem, then maybe deal with the insomnia.

Speak with your physician and a free sample of sleeping aides. Today's benzodiazepines are not addictive like the barbiturates of thirty years ago.

You'll most likely find that after a dew days, you won't need them at all.

Ambien 5 mg (get the 10 mg and break it in half). If that isn't enough, go to 10 mg (standard dose).

If you need something a bit stronger try Restoril, which comes in 15 and 30 mg. Restoril has been around awhile and is available in generic form Temazepam.

I wish you success.
