Im not exactly sure how the E-cigarettes actually work.  I bought one myself from SmartSmoker...and it could be JUST ME but it tasted like a Fog machine.  Not only did it not taste like a cigarette but after taking a couple puffs I felt strange.  I got the nicotine that I needed but I also got a strange feeling in my head (to explain it exactly:  Pressure in my sinus cavitys although there was no flem present, mild blurred vision, dizzyness)  This feeling was not present while smoking normal cigarettes nor was it present before the usage of the E-cigarette. The feeling lasted for a couple hours after I decided to stop using the E-cigarette and the dizzyness stayed well into the next morning when I woke.  Could this be a coincidence?
