I'm using 18 mg. I was a pack a day or more smoker, right now i'm smoking dunhill lights in the blue pack, or normally i did yellow pack American spirits, they aren't supposed to have chemicals..maybe I need to try WTA vapes, or just have more will power.
It is a habit though, a comfort zone i fell back to in a way i guess...
It's like now i've been wanting a good strong tobacco flavor vape with high nicotine, maybe that's what i need instead of fruity stuff and mild stuff, maybe up it to 24 mg, idk
I have started taking an old bottle of zyban that i hadn't really tried before
If you continue to have a hard time, I would recommend WTA, but I would read on it in the threads here so that you are confident in using it. I use WTA and it is what made it all possible for me. Just do a WTA search and see what threads come up - there's a lot of information about it.
