Same, I cut back the past couple of years to the point where I rarely smoke anymore at all and I'm starting to remember the whole reason I started smoking and loved it to begin with - I am extremely high strung to the point of bat shit insanity. Everyone always compliments me for how laid back I am but I'm not, its just a personality trait I developed when I started smoking daily around 19 years old. In my natural state I am straight up type A personality. I'm hyper and annoying and stressed out constantly. Pot was a godsend for me.
I would hope that in that 5 minutes I was able to tell my children that I loved them and that they should move ahead and remember all the good times we shared. I never let a day go by without telling them but hope it would bring them some comfort and help them. Then I would ask for more pain meds.
Since all of my family members are dead, I'd more than likely spend my last 5 minutes on this earth calling my friends, and telling them how much I love them (just hope I wouldn't be reduced to doing it on voice mail)
It's funny, I was thinking of starting a thread with a similar subject recently. I think it was because there was something on PBS about dying and end of life care. I think I would feel at least a little unfulfilled, honestly. I'd probably want to try to take care of any important unfinished business. I guess the best thing to do would be to try to be at peace with it. If you think about all of the people who die young, I suppose it would be better to be grateful for what you've had rather than worrying about what you feel you may have missed.
