I took it over 15 years ago, when they found it helps with smoking. After about 5-7 days of taking 150mg... when I would take a smoke, I got this weird taste in my mouth which encouraged me not to want to smoke, as the taste was soooooooo distastefull!!! Now I'm taking it and it doesn't have the same affect... 3wks later... and so far havent experienced any of the above mentioned symptoms. Would a higher dose acheive the previous anti- smoking affects ?
