It might take a while on NB for you to start noticing an impovement. Especially because you have been so sick. I have been on the protocol for about two months at full dosages and I am only now seeing a few little positive changes. I am more calm, and my emotions are not so up and down. I have spurts of higher energy. But I have to be really careful not to use them up, or I am more fatigued than before. My suggestion to you is just go slowly and give yourself permission to take time to heal.
