I have done many of the same things you are talking about. It does seem logical, but for some reason it doesnt make it easier.
I couldnt even stick to trying to dip some brand other than copenhagen. I was beyond a weak loser.
The fact of the matter is that quitting the first week is hard but changing your lifestyle to quit for a lifetime is much harder. The hardest part is retraining yourself for the long haul. My habits now are posting roll (although sometimes I'm late) and not dipping. I have reinforced those habits everyday for the last forty days through sleepless nights, anger, anxiety, fear, hot flashes, etc. I do know that each moment I am closer to being free from the addiction that has been with me since I was a teen.
Those victories don't start until you DECIDE to quit. No nicotine. Everything else is just a small lie your addiction is telling you to make it easier.
I really hope this helps. All of our beliefs are products of our own quits and failures. Lot's of knowledge from the folks around here. Great info. Make your decision. I hope you join us.
