Hey vibrant, I'm on week 3 of super dmz and I'm damn lethargic too and that's at 400 carbs a day. Ill try to add more quality carbs in morning like you said heavy suggested. I'm irritable as shit I've noticed and the back pumps are trying to kill me I think lol other than that I fucking love this shit. Up like 20lbs, looking swole all the time just wish the back pumps would subside. Trying to get lots of water and taking 12grams taurine every morning but going to add pre workout too cuz that's when its the worst. Glad yours is going well. You having any of the other same issues I am?
