We have a friend that wants to quit and switch to vaping, and everytime he takes a hit off of hubbys ego, he chokes half to death as well. i explained to him that it IS normal due to his lungs being so damaged from smoking, heck it chokes me first thing in the morning with my first hit! but he HAS been able to use a Fifty-One brand of junk ecig with their basic 18mg tobacco flavor -yuck- without choking at all. less throat hit and vapor, me and hubby found this one gross, but it has been working for him with not choking...now if we can get him past the "image" of getting strange looks when he tries to use it..silly men!
even if your hubby just tries to use it at his leisure, while watching tv or relaxing, taking different draws and just experimenting with how it feels, he may be able to get the hang of it!
