"The Bernise method is difficult to maintain" In which way? Please explain. I found it worked amazingly well, as I really thought I would never be off Fet/H again, as I have been really trying for some time, and I have now not smoked any for 5 days, it's super simple really, just start low around 0.025mg of Bupe 1-2x per day, on day one, 4x 0.5mg day two, and 0.5mg 6-7 times on day three, then I did 8mg in 1mg and 2mg pieces over day four, which was also the last day of smoking Fet/H, and been taking 6mg of Bupe every day since, tomorrow I move down to 4mg of Bupe etc.
So as long as you have some Bupe, you have a very good chance of beating it.
