I enjoy the surprise too much, so a spreadsheet or app would take away the fun. My smoking experiences usually go like this. "Hmmm... a J21 sounds pretty good right now." I open the cooler and find 5 other things I'd rather smoke, been meaning to smoke, etc. before even finding the J21. "Out of sight, out of mind." I guess my wife telling me my memory is chit is starting to hold some water
