It's good to have self-discipline in all aspects of life and certainly when it comes to one's health.
I'm respect of my injections, they happen every time I eat (before I eat) and it will continue until the day I die. That's just how it is. Side effects? Well, I get to stay alive.

I think staying alive is preferable to the alternative, at least for now anyway.
You'll be fine, I have no doubt .... when the other thing happens... that's a long way off!
But it won't be soon.... I know, I'll be gone and I'm not afraid, I know some things about those...
