You might experience so called detox symptoms. As the body tries to excrete VA serum levels might raise, and you feel worse than before you started going low VA. I'd recommend you stick to it and see where it goes. It's a long process. It took years to reach toxic levels of VA. I'm in my second year doing low VA and I feel like I'm going in the right direction, but I'm still often sluggish and fatigued.
You can blame it on "detox" as long as you want, but when you don't feel good after doing it for 1 year already, I would change it up.
