I was on it, and ended up with panic attacks as a result. It' helped when I quit smoking, but, afterwards, it led to the panic attacks. And my counselor said that it is not unusual. Many people get anxiety as a result of it.
In fact, when I first tried quitting years ago, I took it. That's when my anxiety and depression first began.
It is also the same time that my son became a heroin addict; and my ex was gambling away the house!
I guess there are times it's just impossible to separate the issues.
Shalom!
Shalom!
