i tried it and got a bad migraine from it. so bad in fact i had to go to the ER because i was puking and couldnt open my eyes. not everyone has a reaction like that. some it works for some it dont. i finally quit pretty much cold turkey when i was told last november it was causing me to have strokes. i did use the nicotine patches for a few days but the longer i thought about what i was told the easier it was to just give up. good luck! it is a battle. i have been smoke free for a year now and hubby has been smoke free for about 9 months! i cant be around it due to the strokes. we both still have cravings.
