I quit the analogs about 5yrs ago and lasted about 6 months and then got started again for what ever reason. Anyway during that time i found out something really strange, not only did i crave the chemicals but also the hand to mouth action. The perfect substitute for me were lillipops and plenty of them. I am a 2 pack a day person, problem is i gained 12KG's (about 28pounds) in 4 months, not to mention what it did to my teeth and sugar levels. Now i havent seen it mentiond anywhere but the weight gain often associated with giving up the analogs does not seem to be a problem when using a pv.
