What affects your process as you reboot

I've been waiting forever to decide if nofap was the place to connect with as I strive for my sexual liberties. What I want to know is if anyone ever realized complications health wise while rebooting and abstaining from sex.

I've read something about how the adrenal glands in our bodies can truly take a toll in our bodies when we masturbate too often, hence the back pain and lack of stimulation. Duly noted that we can heal, but did anyone have to play with this to succeed? I've noticed coffee and cigarettes kill my efforts to obtain an erection and I'd be on reboot for 3 months. Been off cigs since. Coffee is a back and forth problem. And I don't eat ideally. What would any of you suggest to further my erection recovery?
