Thats strange...when I stop smoking for only a week, or even just a couple days I notice that I get much higher than when I had been smoking every day. The only thing I can think of that has made me feel higher was to get some physical exercise before i smoked to get my blood pumping. Run around the block a few times or run on a tread mill untill you break a sweat and feel tired, then smoke. See if it helps.
