Bought some Herron nicaway lozenges. 
4mg, $30 for 132. Compared to $30 for 60 of the nicabate minis. 
Good value but disappointing product, big lozenges that are less comfortable on the upper shelf. 
If they release faster it might be worth it. Was considering the gums again because they give a big kick but barely last 10 minutes. 
Might have a go at buying zyns or similar pouches online, they seem all the rage overseas and go up to 6mg.
