NB - duration of detox and extreme fatigue symptoms ?

Hey forum:
I'm sorry for doing this, but I really need as many responses as possible, it may be life-changing to read different experiences. This was posted on the AF forum, didn't know about this forum. Please read through really fast or skip to the *QUESTION* part.

--------------------------------------

This month marks my official first entire year of NB. Enemas started in August (2012) though.

I know it is constantly repeated that NB takes a long time, but I must say, I've had AF for a total of 7 years now, and the only pattern has been a constant slide. Every day I've felt worse than the previous, with certain periods more obvious than others.
Like this past month, I feel NOTICEABLY more tired than the previous day, it's crazy I don't know when this will end. I feel like I'm already at a threshold, ready to pass out, and I 'know' tomorrow's even worse.

I quit everything (smoking, wrong foods etc...), have picked up yoga on occasion; can only do enemas every 2-3 days (because so fatigued) - the only thing I can see now is self-gratification. This is especially hard to stop, as my body feels so 'wrong' it needs smt good, like a treat. But I'll try to quit that for a while and see...I'm a guy btw (maybe someone can relate ?).
And sleeping. A big problem, can't seem to fall asleep before 2:30am and wake up before 10:30am, and I think the fatigue comes from this too in a big way...

*QUESTION*
For those of you who've done/are doing NB, I'd love to read the most feedback possible on this: how long has it taken for you to start feeling better, as opposed to WORSE, with NB ? A year or even more anyone ?
Ever felt like you're just never ever going to heal ??

I'm still hopeful of course, but I've fought for 7 years now, intensely...no sign ever of feeling better.

On paper, I'm doing great each month, releasing copper etc...; but I feel like I'm dead.

THANKS !
