Two things happened.
Firstly I started training cardio for the first time in years. I bought a elipse machine to have at home. I have only used it twice for 20minutes last thursday and today and am already feeling a lot more motivated and positive. My body is telling me it’s happy to get excersise.
Second I started supplementing with taurine which is supposedly the most abundant amino acid in the brain.
I felt some positives from supplementing with NAC before. Now I learned that NAC, glycine and glutamate are precursors to taurine. Anyways I feel that taurine might be helping me even more than NAC. At least worth checking out for those who have positive experience with NAC.
