anxiety
"I was a major addict (meaning like 5 blunts a day), and was having trouble quitting. Every time I would stop smoking I would have major anxiety attacks. I would get super angry over small things, snap quickly, yell at my girlfriend, and crave smoking like crazy because I knew the anxiety came from not smoking. As soon as I started smoking again I would feel fine. So I quit again, but this time I started an Ativan regimen and am now smoke free. The side effects of feeling tired or a little lazy, doesn't compare to the side effects of smoking, being a bum and having no motivation. I wonder if this would work for cigarette smokers?"
