I used the BE 103 along with cigarettes for a month. Then i got the Joye 510 and have been using that with a few cigarettes a day for about two weeks. Today is day one with no cigarettes. I have been awake since 4 am and just using my Joye 510. It's going ok. I really hope these cravings go away. The hardest time for me is when i first wake up and right after i eat. I think if i can get past those times of the day, i should be able to quit cigarettes for good. Wish me luck.
