Mighty D how are you doing on your good fats? You may need to up those to help with fatigue and irritability. If I am trying to go low cal on any given day I might do one meal and snack on Kerrigold(2tbsp) to stave off hunger. Butter has no lactose since it's just cream, you maybe able to tolerate it. My 2 cents. Keep on climbing back up those trees and getting your Tarzan on!
