You won't get a nicotine feeling. The buzz of cigs is the carbon monoxide and carbon dioxide you are breathing plus 4000 assorted chemicals including carpet glue - you are asphyxiating yourself when you smoke. With ecigs, other than nicotine's TH, the only nicotine feeling you will get is if you get too much - headache, rapid or irregular heartbeat, cold fingertips, exhaustion or just feeling sluggish and ill.
Some say most of the nicotine is absorbed in your mouth. I don't know.
