I was chewing fake stuff as well and have pretty much put it down for the last month or so. I am at 6 months quit. Your lip is used to having a bulge in it and it takes time to get away from that need.
I agree, I've only been quit for 5 days but the weeks leading
up to the quit date, I slowed down from a can a day to a can
every three. I chewed in my upper lip for 20+ years. After the
doc told me to quit, or at least move it around. I started chewing in my lower lip. At that point, I was craving a dip
even though I had one in my lower lip. I was still grasping
for the can.
Today, I find my self, unconsciously, still grabbing
for the can.
