Your quit is unique, for sure. But technically I'd say you quit cold turkey. You didn't have any nicotine going into your system while you were in that coma. So your body detoxed the same way a person who actively quits cold turkey would. You just didn't feel the effects while you were unconscious.
You could always share with your acquaintance the experiences you've read about on quit forums like this one. I'm sure you have absorbed enough from all of us to be able to give someone insight into quitting cold turkey versus using NRT.
As WhispersQSMB said above, everyone's quit is different. That's really all we can definitively tell a person who is thinking of or in the process of quitting. Some people quit successfully with the help of NRT. Some struggle with using NRT. Some use NRT properly. Some don't. Some become addicted to NRT. Some quit cold turkey easily. Some struggle and have to hold on by their fingernails. Some only struggle for the first few weeks. Some struggle for years. It varies so much from person to person.
The one universal truth, I'd say, is that a successful quit is always achieved by adhering to the concept of NOPE one day at a time.
Sorry for the long and rambling answer!
