Forcing it has never worked, but I am sure it will gradually go down. I have gone down from 22/23 a day to 16/17 a day. I also try to avoid inhaling cigarettes, which works sometimes. Also, recently the stubs are growing longer - ie I smoke 2/3 instead of a full one.
I really recommend you check out Swedish snus. Snuscentral.com has a wide variety. The shipping to the US is steep, so you have to order in bulk to make it worth it, but it's much better for your health, and should end up cheaper than cigarettes by a decent margin. If you like straight tobacco flavors, check out Ettan and Grov. Grov has a strong (stark) portion that you might enjoy, too.
Highly, highly recommend snus. The nic hit doesn't feel quite the same, but it is enough to be satisfying. If you need a super quick nic hit, try some snuff. MrSnuff.com has the best selection, and there's plenty of high nic snuffs out there to help get that fix quickly.
