I 100% feel you as the fear of having to do it forever was a big hold up for me as well. The reality is you can stop whenever you want you will just go back to having less energy etc.
Having done it I can see myself doing it until my late 50's at which point I should have the majority of my adventuring done as well as be out of the workforce so I will probably not be too concerned about lack of energy.

I am not sure if you go back to your previous baseline. I know athletes who do this have forever left with way lower testosterone than their previous baseline.
