This may be a silly thing to ask, but for low-hanging fruit, has Eliazer ever tried just the vitamin stack from this? Or just taking a whole lot of vitamin B? My own soylent experiment failed because I couldn't make anything that tasted decent, but I also have mysterious low blood sugar (haven't talked to a dietician, but the basic advice like eating protien and avoiding simple sugar isn't enough to make me not get hungry every two hours), and the emergen-c vitamin from my soylent seems to help. (I have not blind tested this yet, so my confidence that it's not a placebo effect isn't too high.)
