Man, I been smoking everyday for 41 years, but its been like 4 or 5 years since I ran out and had to skip a day of smoking. And Actually, I did not run out then, I had to go out of town and had no way to take it with me on the plane. (Now I take HASH with me when I fly)
But I have had to skip a day or two days out of town with no smoke and I had the blues and no appetite, but I did not get the jones or shakes or anything.
