I know what you are experiencing. When I was single, I smoked about a pack a day for a year, mostly in the closet. Then I got married to a non-smoker, and have been a light smoker ever since. Sometimes, I will go on a binge, closet smoking, and smoke about a half a pack to a pack a week. I binged this week, and it was most enjoyable. Graduated from lights to marl reds...enjoyed the full flavor but the reds burn faster. Perhaps will try Reds 100s next.
Typical closet smoking routine. Smoke on way to work before getting on subway...which gives me about 30 minutes for the small to go away. Smoke before I eat lunch; eat lunch away from work; and then wash hands thoroughly. Smoke on way back home before boarding subway...etc.
