Update

I eventually purchased Walgreen branded 21mg 24 hour release patches, which I cut into 4 equal doses. I use them for days when I go weight lifting or bouldering. I feel a noticeable alertness when I use the patches. I did not notice any increase desire to smoke and have no noticeable cravings on days when I am off the patch. I decided to stay away from any instant forms of nicotine such as e-cigs or gum.
