I have also tried juice fasts in the past, only for a few days at a time, a month might drive me crazy! But yes, eating less (especially less carbs) does seem to lead to more mental clarity - which is kind of interesting, because you'd expect it to be the opposite!

Thanks @sequentialvibe! I go to the gym for my workouts, sometimes I'll do some abs/pushups at home if I'm hanging around and have extra time/energy.
