Cool. Ex 4 pack a day 30 year habit here.
I hit a slump around that point also. I think everyone does. Hang in there, switch up juices, maybe try a new delivery method or different resistance.
I mostly vape sweet flavors, berry,butter cream icing, caramel, butterscotch, etc but I like a well made natural tobacco every now and then.
